List of HP Fests & Communities by Category

[lee_bella]

Updated on December 1, 2024: Reorganised a few things. Added Moony's Midlife Crisis Fest, Harry in Lingerie Fest, HP on Broadway Fest, Ronarry Fest, etc. Also added Bluesky links to several fests.

This is a list of Harry Potter fests, HP communities and other HP fandom events organised by category. With a few exceptions, most of the fests and communities below are active from 2019 and onwards. Some of these fests have gone defunct, and the links might not work.

Acknowledging that you noted this post is a work in progress, I thought I’d mention the HP Podfic Fest (2011-2019) just in case. It’s on LJ https://hp-podfic-fest.livejournal.com/ and DW https://hp-podfic-fest.dreamwidth.org/
(I didn’t see it here; apologies if I overlooked it.)
