Live at the Beacon Theater is the fourth full-length comedy special/concert film by comedian Louis C.K. The special takes place at the Beacon Theatre in Manhattan, New York.

In contrast to his previous specials, which had been produced for broadcast and sale on physical media, Live at the Beacon Theater is sold directly from the comedian's website for the cost of $5.00 USD and can be downloaded in 720p HD or streamed in browser. Also in contrast to his previous special, Hilarious, which was released for sale more than a year and a half after it was recorded, Live at the Beacon captures a performance from just a month before its release (November 10, 2011). It later aired on the FX television channel. It later was made available in a Humble Bundle.

As stated in the end credits, the film was dedicated to comedian Patrice O'Neal, who died two weeks prior to its release. C.K. considered O'Neal one of his favorite comedians.

The film won the Primetime Emmy Award for Outstanding Writing for a Variety, Music, or Comedy Special and received three other nominations.

C.K. re-released the DVD, video and audio album for download and streaming on his website in April 2020.
