Marie Mahder (December 3, 1923 – January 28, 2001), better known by her stage name Sally Mansfield, was an American television character actress; she also had a few small roles in feature films including one with Dean Martin and Jerry Lewis.

[citation needed] She is perhaps best remembered, however, for her 1954 role as spaceship navigator Vena Ray on the syndicated science fiction show Rocky Jones, Space Ranger.

Her character anticipated Nichelle Nichols' much more famous role as a female spaceship bridge officer on the 1960s television series Star Trek.

The same year Mansfield carried the Miss Emmy torch at the Palladium during the sixth annual Academy of Television Arts & Sciences awards banquet.

[citation needed] Executive Producer, Guy V. Thayer Jr., signed Richard Crane and Mansfield to five-year contracts for Rocky Jones, Space Ranger.
