geeky halloween costumes for families

If you’re a nerdy mom, there’s a good chance you also love Halloween.

It’s the one day of the year it’s acceptable to dress like your favorite characters from the movies, TV shows, video games, or books you geek out over (unless you are a cosplayer of course, in which case you dress up all the time!).

Hopefully, you’ve passed on the geeky gene to your kiddos; then the whole family can dress up together! Whether you like to DIY your own family Halloween costumes or just buy ready-made ones online, Halloween is a time to let your nerd flag fly.

These geeky Halloween costumes for families will give you some ideas for nerding out with your kids this Halloween.

1. Guardians of the Galaxy

How cute would a Baby Groot costume be for the baby in the family? Guardians of the Galaxy can easily work for the whole family with Dad as Starlord, Mom as Gamora, and another child as Rocket.

2. Star Wars

If you’re a Star Wars fan, there are a lot of Halloween costume options. Whether you’re a hardcore original trilogy fan or a newer fan of the most recent trilogy, you can dress like your favorite characters. Princess Leia, Darth Vader, Rey, and Kylo Ren are some of the most popular choices. Storm Troopers, Ewoks, droids, and porgs also make fun geeky Halloween costumes for families.

Costumes from The Mandalorian would also make an awesome Star Wars theme for families. Ramona from the Fab Everyday blog and her family really rocked these DIY Mandalorian costumes.

This is the way. DIY Mandalorian Halloween costumes! . Because we love Halloween so much, and because 2020, we decided to do more than one Halloween costume this year. We figured why not get extra festive and spend some time celebrating and dressing up as the things we love (see our Hamilton costumes that I shared last week). Our family LOVES @TheMandalorian series, and we have watched it all the way through several times. Because of how much we love it (and @StarWars in general – you might remember our @StarWarsMovies: The Force Awakens costumes from a few years ago), this choice was a no-brainer! We got really into it, and decided to DIY everything 1) to save money (the really good cosplay ones on Etsy are REALLY pricy), 2) because not all of these costumes exist yet, and 3) because we love an excuse to get crafty. The hubs had to be Mando, AKA Din Djarin (the Mandalorian), I chose to be ex-shock trooper Cara Dune, Grayson decided to be the bounty-turned-nurse droid, IG-11, and Sawyer chose the Ugnaught Kuiil as his character. You’ll be surprised at how some of these came together! . 🚀 Get the details and DIY instructions on Fab Everyday: http://bit.ly/MandalorianCostumes (link in bio) 📍 Pin for later: https://www.pinterest.com/pin/147563325280384020/ . #FabFam #Halloween #halloweencostumeideas #familyhalloweencostumes #costumeideas #halloween2020 #diyhalloween #diyhalloweencostume #fabeveryday #mandaloriancosplay #mandaloriancostume #thisistheway #ihavespoken #caradune #dindjarin #kuiil #ig11 #starwarshalloween #themandalorian #blurrg

You could also pay homage to the new Ahsoka series. How about Ahsoka, Sabine, Huyang, Hera, and Ezra for your family?

3. Avengers

The Avengers offers a lot of possibilities for Halloween costumes. Our family did Avengers last year, with my husband as Thor, me as Black Widow, my son as Iron Man, and my daughter as Captain Marvel. This family included a Dr. Strange, Black Panther, and an adorable little Spider-Man.

For a cute Avengers theme in a family with an expecting mom, why not do out-of-shape Thor like this family!

4. DC Comics

Maybe DC is more your style. I love this family’s combination of Superman, Wonder Woman, Batman, and Robin.

5. Lord of the Rings

Lord of the Rings fans have a lot of Halloween options too, but a whole family of hobbits would be something unique. Any combination would be super cool, though. I love the inclusion of the Witch King in this family!

Adventure awaits ‘round the bend, Where the misty shadows lie. Where some shall fall, some shall live, And some shall surely die. Beware the winding, twisted road, Which none should go astray. If you should doubt, and lose all hope, Swipe right, it’s the only way. And so, I leave you with this thought below from one I so admire, and wish you HAPPY HALLOWEEN, now it’s off to the shire! – “One Ring to rule them all, One Ring to find them, One Ring to bring them all and in the darkness bind them.” ― J.R.R. Tolkien, The Fellowship of the Ring — . . . . . . . #halloweencostume #halloween #halloween2019 #thering #thefellowshipofthering #jrrtolkien #halloween🎃 #halloweenfamilycostume #familycostume #myfamily❤️ #interiordesigner #losangeles #momlife #homemadecostume #homemadecostumes #2019halloween #kvinteriors #lovefortheholidays #spookyseason #familyphoto

6. Mario

Here’s one for the gamers! If you are a Nintendo family, Mario, Luigi, Peach, or Link and Zelda are all fun Halloween options!

7. Baldur’s Gate 3

Baldur’s Gate 3 is one of the most popular RPGs right now, and with good reason. The game is phenomenal. Be on-trend with your Halloween costumes this year and go as companions from the game. Astarion, Karlach, Shadowheart, or your own original player character make great family Halloween costumes.

8. Pokémon

Kiddos make adorable Pokémon. Gotta catch ’em all! Heather from Our Happy Healthy Homestead and her family really nailed their Pokemon costumes!

9. The Little Mermaid

Disney nerds might like the cast of The Little Mermaid for family costumes.

10. Firefly

I couldn’t find any photos of families dressed as the Firefly cast that I could use for this post, but I know this show has a decent-sized fandom so I wanted to include it! The costumes would be pretty easy to DIY – I would think you could find many of these items in local thrift stores.

11. The Incredibles

The Incredibles are a family of superheroes, making them an easy choice for a family costume idea, especially a family of two or more kids.

12. Harry Potter

If you’re a family of Potterheads, represent your favorite Hogwarts house like this family.

13. Hamilton

Any history nerds here? Dressing up as important figures from the American revolution is a nerdy costume that is unique. You could choose any formal colonial costumes to become a figure from the revolution, or specifically aim to look like a Hamilton cast member.

Where are my #HamilFans at?? Raise a glass to the four of us as we debut our first family Halloween costume of the year (yes, I said “first;” more on that later): ⭐️ Hamilton! ⭐️ I’ve got details, links, and instructions for how we put our family Hamilton costumes together on FabEveryday.com (link in bio). . Since @HamiltonMusical came out on @disneyplus in July, we’ve watched it more times than I can count. It seems I can never be satisfied. Whenever someone suggests we listen to the soundtrack or put the film on TV, I don’t know how to say no to this. I’m pretty helpless, actually. So when the family showed interest in dressing up as characters from Hamilton for one of our Halloween costumes this year, I decided I was not throwing away my shot. 👆🏼 I had to be the 10-dollar-founding-father-without-a-father himself, A. Ham, Grayson chose to be John Laurens, Sawyer had to be his favorite character (and America’s favorite fighting Frenchman), Marquis de Lafayette, and the hubby was, that’s right, Hercules Mulligan! We wanted to be these four so we could raise a glass to freedom together. . Our costumes include some store-bought parts with some easy DIY upgrades, and we are really happy with the results. Check out the details on Fab Everyday today, or if you can’t read it now and you’re willing to wait for it, make sure to pin it for later. You’ll be back. . ⭐️ Get the details on Fab Everyday: http://bit.ly/HamiltonCostumes (link in bio) 📍 Pin for later: https://www.pinterest.com/pin/147563325280340902 . OK, HamilFans… can you count the number of Hamilton song references in the caption? . #FabFam #Halloween #hamiltonmusical #hamiltoncosplay #hamiltonhalloween #halloweencostumeideas #familyhalloweencostumes #alexanderhamilton #johnlaurens #herculesmulligan #marquisdelafayette #hamilfan #hamilfan #hamilfilm #raiseaglasstothefourofus #costumeideas #halloween2020 #diyhalloween #diyhalloweencostume #fabeveryday

14. Roman/Greek Myths

Another great history themed costume for families would be figures from Roman or Greek mythology. The possibilities are endless, from gods and goddesses to famous historical figures.

15. Astronauts/Aliens

A family of science geeks would be perfect for space-themed costumes. Aliens, astronauts, and rocket-ships!

16. The Labyrinth

The Labyrinth was a 1986 fantasy film starring Jennifer Connelly and David Bowie that has since gathered quite a cult following. Sarah, Jareth, and Toby would make fun costumes for a couple with a baby! You could buy pre-made costumes, but this one would also be pretty easy to DIY.

17. Game of Thrones

You may or may not have liked the ending, but there were a lot of excellent and memorable characters from Game of Thrones that would make great costumes. You’ve got lots of options, but Daenerys, Jon Snow, and baby dragons would be cute for a family.

18. Overwatch

This cosplaying mother-daughter duo went ALL OUT for these Overwatch costumes. Such amazing talent!

19. Power Rangers

Whether you’re a family of two or six, you can make Power Rangers costumes work. Love these cute little Rangers!

20. Anime

If you’re an anime fan, there are TONS of costumes you could make work for a family. The possibilities are endless!

How cute is this Dragon Ball Z family (costumes made by @moth.mama)? This could be a really fun one to DIY.

Here’s a family that did Soul Eater!

And this family really went all out with these My Hero Academia costumes!

Bonus Costumes

I found these costumes after I had already published the post, but I loved them so much I had to still include them.

What fun costumes from The Princess Bride!

And this family’s Dr. Who cosplay is so geeky – in a good way of course!

Well, there you have my ideas for nerdy and geeky Halloween costumes families. What are you and your family dressing up as this year? Are there any other great geeky costumes I missed? Tell me in the comments.
