NBC said Monday that Mikey Day, Alex Moffat and Melissa Villasenor will be on board as featured performers for the show's Oct. 1 season premiere.
Villasenor, of Whittier, California, will be one of the few Latino cast members in the history of the show, which has come under fire for a lack of diversity.
She's an impressionist and stand-up comedian who's appeared on the club and college circuit nationwide. Villasenor also performed with Mas Mejor, a comedy studio and network launched by "SNL" producer Broadway Video and aimed at finding new Latino talent.
Day, from Orange County, California, joined "SNL" as a writer in its 39th season and was a co-head writer and cast member on NBC's variety show "Maya & Marty."
Moffat is from Chicago and was a regular performer at iO Chicago and The Annoyance Theatre.
Last month, "SNL" said goodbye to two cast members, Taran Killam and Jay Pharoah. The long-running show is known for its changing slate of performers.
