Late Night with Conan O'Brien is an NBC talk show hosted by Conan O'Brien that aired from 1993 to 2009. The second incarnation of NBC's Late Night franchise, O'Brien's debuted in 1993 after previous host David Letterman moved to CBS to host the Late Show.
From 1993 until 2000, Andy Richter served as O'Brien's sidekick. The show's house musical act was The Max Weinberg 7, led by E Street Band drummer Max Weinberg. In 1997 the show launched the career of Triumph, the Insult Comic Dog, a popular recurring character of Late Night performed by then-head writer Robert Smigel.
During O'Brien's tenure with Late Night, the dressing room featuring the closet with the Muppet Pipes belonged to Max Weinberg. When Jimmy Fallon took over the show, the dressing room was demolished and the pipes were put behind glass and added to the NBC studio tour.
- Kermit the Frog made a guest appearance on the show in its second season, appearing on September 23, 1994 to promote the releases of Muppet Classic Theater and Kermit Unpigged. Other guests that night included Kevin Nealon and Leonard Maltin.
- Quentin Tarantino made an appearance on the show just prior to the initial airing of The Muppets' Wizard of Oz to promote various projects -- a majority of the interview was spent talking about his experience with the Muppets and his love for the characters.
- Andie MacDowell appeared on the show in 1999 to promote Muppets from Space and talked about her cat fight with Miss Piggy. A clip of said fight was shown.

- O'Brien jested in the monologue of his March 11, 2006 show stating, "The producers of Sesame Street say they have decided not to ask Russell Crowe to appear on the show because they don't think he's a good role model. Crowe is upset because he really wanted to host the episode sponsored by the letters 'F' and 'U.'"
- In an "Actual Items" segment from a November 2007 episode, Conan shows an advertisement for Sesame Place, with photos of Oscar the Grouch, the Cookie Monster walkaround, and an illustration of Ernie choking Bert to death.
