Gregory Sebastian Fitzsimmons (born April 5, 1966) is an American stand-up comedian, actor, podcaster, and Emmy Award-winning television writer.

Fitzsimmons was raised in Tarrytown, New York to Bob (1939-1993) and Patricia Marie Judith (née McCarthy) Fitzsimmons. Greg's father was a New York City radio and television personality who was one of the original presenters of Good Day New York and was a host of the Jerry Lewis Muscular Dystrophy Telethon from 1973 to 1989.^[1]

Greg began his stand-up comedy career while attending Boston University, where he earned his undergraduate degree and was part of comedy troupe Uncontrolled Substance.^[2]

Fitzsimmons made his late-night debut in 1996 on the Late Show with David Letterman.^[3] That same year he began hosting MTV's Idiot Savants which received a CableACE Award for Best Game Show Special or Series.^[4]

Fitzsimmons served as a writer on the first three seasons of The Ellen DeGeneres Show for which he received one nomination and four Daytime Emmy Awards. In a 2010 interview with Howard Stern, he described the work environment as "toxic."^[5] A decade later these allegations were substantiated in an exposé by Buzzfeed News citing the experiences of ten former employees.^[6]

From 2004 to 2009 Fitzsimmons was a regular commentator on Vh1's Best Week Ever and from 2010 to 2014 he made over 40 appearances on Chelsea Lately.

There were several memorable moments over the course of the series including his interview with Andy Dick that resulted in Dick being banned from the channel over antisemitic comments toward Stern in 2011. The final episode of The Greg Fitzsimmons Show aired in 2018.

Fitzsimmons has toured the United States as a stand-up comedian and has performed on such programs as The Tonight Show with Jay Leno, Late Show with David Letterman, Late Night with Conan O'Brien and Jimmy Kimmel Live!.
