Mitzi Gaynor Donahue (born May 2, 1964 in Yorba Linda, Orange County, California) is an American actress, also credited and more popularly known as Mitzi Kapture. (Mitzi Gaynor was a popular stage and film actress in the 1950s).

Kapture began her career in films, most of which were not huge commercial successes. She went on to make a few television guest appearances (MacGyver, 1st & Ten) before she gained international exposure with her first major television role as Sergeant Rita Lee Lance in the television series Silk Stalkings. Silk Stalkings premiered on CBS but later moved to USA Network. "Silk" aired for 8 seasons and became one of USA network's highest rated original series. Kapture's role as Rita, the other half of the two "Sams" for almost 5 years, cemented her popularity. Paired with Rob Estes (Melrose Place, I Do, They Don't) who played Sergeant Chris Lorenzo, Kapture gained global recognition along with her costar since the show was broadcast in several countries. They were nicknamed the "dynamic duo" by fans. Kapture garnered much praise for her strong portrayal of the character who was a role model for many young women. Sergeant Lance eventually became Lieutenant Lance by the time Kapture left the series in 1995 to have her first child Madison. Her departure from the series together with that of co-star Rob Estes left many fans protesting. During her time with the series, Kapture briefly sat in the director's chair, for two episodes. She was interviewed for the Silk Stalkings Season 1 DVD which was distributed by Anchor Bay Entertainment and released in September 2004.

After a short hiatus from the screen following her exit from Silk Stalkings, Kapture returned in 1997 to the small screen and USA Network. She played lead roles in two USA Pictures Originals telemovies, Perfect Crime (based on a true story, also called Hide and Seek: The Joanne Jensen Story) and His Bodyguard. She later starred in a few other independent film projects and theatre productions and had several television guest appearances. Kapture also had a recurring role on Baywatch as Alexis Ryker, helping to boost the show's ratings from 2.8 to 4.2.

More recently she played Anita Hodges on The Young and the Restless from 2002 through 2004, where she was credited as Mitzi Kapture Donahue, and starred in the made-for-TV movie Night of Terror which premiered March 262006 on Lifetime Network.
