Kaili Vernoff (born Jan 13, 1974) is an American Actress. While she has many television and film credits, she is perhaps best known for her multiple collaborations with Woody Allen.

Kaili Vernoff was born in Los Angeles, California and lived in many cities as a child, including Park City, UT and Troy, NY. She attended Boston University where she received a BFA in acting. She moved to New York City upon graduation, where she has lived and worked ever since. Her first feature was the Ed Burns' film, No Looking Back (1998), in which she played "Alice". Soon after that, she worked with Woody Allen for the first time in his film Celebrity (1998), and while she ended up on "the cutting room floor" of that film, Mr. Allen wrote a role for her in his next feature, the Academy Award nominated Sweet and Lowdown, in which she played the role of "Gracie" opposite Samantha Morton and Sean Penn. She has appeared in six Woody Allen projects in total, most recently in his first foray into television, the Amazon series, Crisis in Six Scenes. She has worked steadily in film, television, and theater. Other notable roles include "Kerry Ridge" in the Hulu drama The Path (2016–2017) and "Karen" in the film Thoroughbred, which will have its world premiere at the Sundance Film Festival in January 2017.
