Ona Zee (born Ona Zimmerman on March 3, 1954 in Los Angeles, California , U.S.) is a Jewish-American porn star and model.

Ona Zee has made about 300 adult movies; for a few of those, she served as director, writer and producer. She has become known within the industry as one of its most stable personalities, often being described as a strong ally and friend to those in need. She strongly opposes illegal drug use and/or sale, and advocates against young stars getting caught up in that world.

Late in her career, she appeared on The Oprah Winfrey Show, along with porn actress Nina Hartley, to discuss the porn business. Well-known as being articulate and outspoken, both she and Hartley defended the industry, despite a very hostile mostly female audience. Both stood firm on their views, advocating free choice and freedom of speech.
