About Alien Day

Alien Day is an annual fan and franchise celebration held on April 26 for the Alien film series.

Twentieth Century Fox Consumer Products launched the global fan-focused event in 2016, choosing 4/26 as a reference to LV-426, a location central to Alien franchise lore.

Why Alien Day matters

Alien Day is an entertainment-franchise observance, not a civic or public holiday.

Fans often use the date to revisit films, games, books, collectibles and licensed releases connected with the franchise, while third-party fan participation does not imply endorsement or affiliation with the rights holder.

History of Alien Day

Twentieth Century Fox Consumer Products announced the first Alien Day for April 26, 2016 as a 24-hour fan-focused global event.

The launch explicitly explained the April 26 date as a nod to LV-426.

20th Century Studios’ current Alien page preserves official Alien Day and Alien Day 2017 material, confirming the event’s continuing place in the franchise’s first-party history.
