Geek Pride Day is an initiative to promote geek culture and is celebrated annually on May 25th. It is for anyone who appreciates sci-fi, fantasy, board games, video games, comic books, cosplay, anime, steampunk, zombies and related fandoms.

The formal initiative was originated by a Spanish blogger in 2006 as Día del orgullo friki and has spread throughout the world, primarily via the Internet.

Tim McEachern first organized a series of events called Geek Pride Festival or Geek Pride Day from 1998 to 2000 at a bar in Albany, New York. Then Dick Morley, a “father” of the programmable logic controller, organized Geek Pride Days at his retreat in New Hampshire, called “The Barn,” as early as 2001.

In 2006, Spanish blogger Germán Martínez, known online as señor Buebo, organized the first celebration. The day was celebrated for the first time in Spain and on the Internet, drawing attention from the media. The largest gathering took place in Madrid, where 300 geeks demonstrated their pride with a human Pac-Man. A manifesto was created to celebrate the first Geek Pride Day, which included a list of the basic rights and responsibilities of geeks.
