Brad Williams (born January 13, 1984) is an American stand-up comedian and actor, who was born with achondroplasia.

He got his start by attending a Carlos Mencia live comedy show. While he was in the crowd, Mencia made jokes about dwarves. The people sitting close to Williams were scared to laugh. Mencia noticed this, then noticed Williams and he asked him to join him on stage. Williams cracked a few jokes and impressed Mencia. Mencia then asked Williams to try stand-up and be his opening act on the road. He has been Mencia's opening act ever since, opening up shows on both the Mind of Mencia tour and the popular Punisher Tour.

He appeared on Mind of Mencia, playing several roles, including playing a dwarf whore ("whorf"), the leader of an all dwarf basketball team, joining Mencia at a Renaissance faire, and giving a speech about his hatred of podiums. For St. Patrick's Day 2008, he dressed as a leprechaun, made an appearance on The Tonight Show with Jay Leno. For Halloween 2008, he dressed up as Child's Play character Chucky for a skit on Jimmy Kimmel Live!.

In 2022, he was hired as the lead comic of the Las Vegas Cirque du Soleil show Mad Apple.
