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.

It later aired on the FX television channel. It later was made available in a Humble Bundle.
