Michéal ("Mike") McShane (born June 25, 1955 in Boston, MA,) is an American actor and improvisational comedian who first became known to American audiences through his appearances on the British version of the television show Whose Line Is It Anyway?

McShane had performed on stage, on television, and in film, and was an alumnus of Los Angeles Theatresports. One of his larger TV roles was as Kramer's nemesis Franklin Delano Romanowski (FDR) on Seinfeld. He also had a cameo role as a doomed hypnotherapist in the film Office Space.

In 1995 McShane starred as Harley in the BBC Screen Two TV Movie Crazy For A Kiss, about a young boy who is sent to a mental institution for teenagers in Kansas. Touted as being somewhat biographical of McShane's childhood, the film has never been released on video or DVD.

McShane appeared in Tom and Huck as Muff Potter. McShane appeared in Brotherly Love as the experienced but wisecracking mechanic, Lloyd. His character does not really relate to the story but brings humorous (and sometimes deadpan) one-liners as he shows up. Lloyd can somehow force people to take care of his trouble by taking the battery out of a van, taking car keys, or talking about his appearance.

He provided the voice for Cid in the video games Final Fantasy X and Final Fantasy X-2, and played Friar Tuck in the 1991 film Robin Hood: Prince of Thieves. He appeared in Tower of Terror, a TV movie based on the Disney attraction as "Q" along with Steve Guttenberg and Kirsten Dunst. He had also appeared with Tony Slattery in the comedy sketch show S&M, starred in the sitcom The Big One, and provided voice work in the anime Vampire Hunter D: Bloodlust, as D's sarcastic possessed left hand. He also provided the voice of Detective Twitch in the HBO animated series Spawn. McShane also played the part of and voiced the character of Baron Rakan Harkonnen in the 2002 strategy game Emperor: Battle for Dune.

In 2003 McShane underwent gastric bypass surgery, losing a significant amount of weight.

In 2006 he was slated to appear in a new production of Talk Radio directed by Stewart Lee, but later dropped out due to scheduling conflicts. McShane later said that it "was a huge mistake and I still regret not performing in Talk Radio."

Mike appeared as the voice of Audrey II (as well as playing a number of peripheral characters) in the London revival of Little Shop of Horrors at the Menier Chocolate Factory in Southwark between December 2006 and February 2007. The show was a critical success and was sold out for the duration of its run, and Mike had been contracted to continue in the role following the show's transfer to the West End at the Duke of York theatre. In September 2007 he took part in the British Library's celebration of Jack Kerouac, reading excerpts from On The Road on the 50th Anniversary of its publication.

King-sized actor trained in the classics and in improvisational comedy in Berkeley, California, which took him to England in 1990. One of the first artists to be accepted into the British improv field, he appeared regularly on the comedy panel of "Whose Line Is It Anyway?" (1988).
