On what date did Lost’s series finale first air on ABC? It first aired on May 23, 2010.

The finale, titled “The End,” was a two-part conclusion serving as the 17th and 18th episodes of Lost’s sixth season and the 120th and 121st episodes overall. ABC broadcast it in the United States on May 23, 2010.

The extended finale resolves the island’s central conflict involving Jack Shephard, the Man in Black, and the struggle to protect the island’s light. It also brings the show’s flash-sideways storyline to its emotional conclusion, revealing the nature of the characters’ shared afterlife setting.

The date is easy to confuse with other important Lost milestones. September 22, 2004, was the series premiere, while May 29, 2008, was the date of season 4’s finale. “The End” ran for roughly 104 minutes and was simulcast or broadcast internationally on different local dates because of time-zone differences.
