Sandra Smith (born 27 June 1940; age 75) is an actress from Minneapolis, Minnesota, who played Dr. Janice Lester and Captain James T. Kirk in the final episode of Star Trek: The Original Series, "Turnabout Intruder". Prior to the feature film Star Trek, she was the only actor besides William Shatner to ever play Captain Kirk on Star Trek.
Outside of Star Trek, Smith is best known for her role as Julie Conrad Bauer on the soap opera Guiding Light from 1962 through 1965. Afterward, she acquired a recurring role on the short-lived series Our Private World, during which she co-starred with fellow Trek alumni Nicholas Coster, Michael Strong, and Kenneth Tobey. She went on to appear on such television programs as The John Forsythe Show (with Darleen Carr), The Virginian (in an episode also guest-starring Andrew Prine), The Big Valley (working with the likes of Hal Baylor, Walker Edmiston, Jon Lormer and Michael Strong), Mannix (in an episode with Steve Ihnat), The Bold Ones: The Lawyers (also with Ihnat), Gunsmoke (three episodes), Bonanza (two episodes, including one with Bill Zuckert), and The Flying Nun (with Michael Pataki). On stage, she performed on Broadway in the plays The Pleasure of His Company and Ash Wednesday. She won a 1966 Theatre World Award for her role in the latter play, on which she also co-starred with Kenneth Mars.
During the 1970-71 season, Smith co-starred with fellow TOS guest actors Stephen Brooks and Skip Homeier in the medical drama The Interns. In 1972, she reunited with her "Turnabout Intruder" co-star William Shatner for an episode of Owen Marshall: Counselor at Law (which also featured Bill Quinn). Smith followed this with guest spots on Hawaii Five-O (with Monte Markham and Madlyn Rhue), The Rockford Files, and Starsky & Hutch (starring David Soul) before disappearing from the public eye.
