Ray Walston (November 2, 1914 – January 1, 2001) was an American stage, television and feature film actor who played the title character on the situation comedy My Favorite Martian and Judge Henry Bone on the drama series Picket Fences.

He was born Herman Walston in New Orleans, Louisiana (some sources indicate Laurel, Mississippi) to working-class parents Mittie (née Kimball) and Harry Norman Walston, a lumber man. He started acting at an early age, beginning his tenure as a "spear carrier" rounding out productions at many New Orleans theaters. He mostly played small roles with stock companies, where he not only starred in travelling shows but also worked at a movie theater, selling tickets and cleaning the stage floors. His family moved to Houston, Texas, where he joined the Houston Civic Theater's repertory company under Margo Jones, debuting in 1938.

Walston was very popular with Margo Jones's team of actors before he travelled to Cleveland, Ohio, where he spent three years with the Cleveland Playhouse. He then traveled to New York City, where he made his Broadway debut in a 1945 production of Hamlet. In 1949 he appeared in the short-lived play Mrs. Gibbons' Boys directed by George Abbott, who later cast him as Satan in the musical Damn Yankees opposite Gwen Verdon as his sexy aide Lola. The chemistry between the two was such that they both garnered critical success and won awards for their roles. After a decade in New York theater, he won a Tony Award, and he and Verdon were invited to reprise their roles in the 1958 film version.
