Robin McLaurin Williams (born July 21, 1951) is an American actor, voice actor, and stand-up comedian. Rising to fame with his role as the alien Mork in the TV series Mork & Mindy, Williams went on to establish a successful career in both stand-up comedy and feature film acting.

Williams has done a number of stand-up comedy tours since the early 1970s. Some of his most notable tours include An Evening With Robin Williams (1982), Robin Williams: At The Met (1986) and Robin Williams LIVE on Broadway (2002). The latter broke many long-held records for a comedy show. In some cases, tickets were sold out within thirty minutes of going on sale. After a six-year break, in August 2008 Williams announced a brand new 26-city tour titled "Weapons of Self Destruction". He was quoted as saying that this was his last chance to make cracks at the expense of the current Bush Administration, but by the time the show was staged only a few minutes covered that subject. The tour started at the end of September 2009, finishing in New York on December 3, and was the subject of an HBO special on December 8, 2009.
