Neal Brennan is an American writer, stand-up comedian, director, and producer. He is most popularly known for his work on the Comedy Central series Chappelle's Show, and for co-writing the film Half Baked.

Brennan and Dave Chappelle met as teenagers when both were aspiring stand-ups. Through his older brother, Kevin Brennan, an established stand up comedian and comedy writer, Brennan got a part-time job working as the doorman at Boston Comedy Club in New York City where Chappelle was a frequent performer. They became good friends and collaborated on each other's jokes. In an interview on Inside the Actor's Studio, Chappelle admitted that he and Brennan could not help but see each other as a painful reminder of the box-office failure of Half-Baked and lost touch with each other. Four years later, they rekindled their partnership to create the sketch comedy show, Chappelle's Show, which premiered in January 2003. The duo wrote the sketches themselves with very little outside help.

Brennan appeared in some sketches in Chappelle's Show and is frequently mentioned during Dave's stand-ups.

On an interview on The Oprah Winfrey Show on February 9, 2006, Chappelle stated that Brennan made no attempt to contact him, despite the numerous media reports that Chappelle went to Africa to escape the pressures of running a high-profile show. "How many times do you think he's called his sick buddy since he went to Africa?", Chappelle said and "If he was that concerned about me, then I didn't get the call. I kept the same cell phone number." Chappelle also said, "I don't think he was worried at all." Neal was quoted as saying "You're not well, Dave."

In an interview that appeared in the July 2006 issue of Maxim Magazine, when asked if he would ever work with Chappelle again, he said there was "no chance". http://www.maximonline.com/articles/index.aspx?a_id=7239.
