LEGO Contest Round-Up for March 2026
A new month is here, which means more competitive building! March right on, there’s plenty on offer in our latest lineup of LEGO contests and challenges from across the AFOL community. March 2026 has a bit of everything to offer – and there’s nothing quite like a theme or a prompt to nudge you out of your comfort zone and push you to experiment building in ways you might not otherwise attempt.
We’ve listed them in order of deadline so you can plan your building time wisely—especially in a month that always seems to fly by. Be sure to check the LEGO activity calendar for local challenges and events near you. Some of our fondest memories, proudest builds, coolest trophies, and strongest friendships started with a contest entry, so we hope you’ll jump in and give one (or two) a try.
