The comedian will headline the Oddball Comedy and Curiosity Festival, which kicks off Aug. 23 in Austin, Texas. The 13-date, two-stage tour concludes Sept. 22 in Phoenix.
The 39-year-old Chappelle has occasionally performed impromptu sets in comedy clubs. But he has largely avoided comedy and public life since abruptly leaving his hit Comedy Central series, "Chappelle's Show," in 2005.
Also on the bill are Flight of the Conchords, Hannibal Buress, Kristen Schaal and Al Madrigal.
