Jack Weston (born Jack Weinstein in Cleveland, Ohio, August 21, 1924 - May 3, 1996) was an American film, stage, and television actor.

Weston usually played comic roles, in films such as Cactus Flower and Please Don't Eat the Daisies, but also occasionally essayed heavier parts, such as the scheming crook and stalker who, along with Alan Arkin and Richard Crenna, attempts to terrorize and rob a blind Audrey Hepburn in the 1967 film Wait Until Dark.

In 1981, Weston appeared on Broadway in Woody Allen's comedy The Floating Lightbulb, for which he was nominated for a Tony Award as Best Actor. Other stage appearances included Bells Are Ringing (with Judy Holliday), The Ritz, One Night Stand, and Neil Simon's California Suite.

Weston married twice, first to actress Marge Redmond. They occasionally appeared together, for example on a 1963 episode of The Twilight Zone, "The Bard", that also featured a young Burt Reynolds. Redmond and Weston divorced and he later remarried. That marriage lasted until his death of lymphoma in 1996.

In a 40-year career that spanned Broadway, television and movies, the versatile actor played everyone from sleazy villains to terrifying killers to clumsy comics. His bad-guy roles included a stalker who, along with Alan Arkin terrorized a blind Audrey Hepburn in the 1967 cult classic Wait Until Dark (1967). He appeared in much lighter roles in Cactus Flower (1969), Please Don't Eat the Daisies (1960), and Dirty Dancing (1987). In the latter, he ran a family resort in the Catskills that set the stage for romance between a teen-ager and dance instructor. His stage work included the Broadway hits "California Suite" in 1976 and 1981's "The Floating Lightbulb," for which he received a Tony nomination for his role as the trashy manager. Also in 1981, Weston appeared opposite Alan Alda in _The Four Seasons_, a movie about three middle-aged couples who vacation together. He played a cantankerous dentist obsessed with his Mercedes, which ended up going through the ice into a frozen lake at the movie's conclusion. Other film credits include Stage Struck (1958), Cincinnati Kid, The (1965), Thomas Crown Affair, The (1968), Ritz, The (1976), and Ishtar (1987).

Born in Cleveland, he was a Machine Gunner and USO performer in World War II before arriving in New York to start his theater career.

Born in Cleveland, Ohio, the son of a shoe repairman, Jack Weston began acting at the age of ten. Encouraged by his father and a perceptive teacher in his public school, he was brought to the Cleveland Playhouse, where he joined their children's theater. He stayed with the company until he was drafted into the army at the age of 19. After his stint in the military he moved to New York, where he appeared on Broadway in "Bells Are Ringing" with Judy Holliday. He spent 18 weeks on the road in James Leo Herlihy's "Crazy October" with Tallulah Bankhead and Joan Blondell. He later won rave reviews as Gaetsno Proclo in Terrence McNally's "The Ritz", a role he later recreated in the film version. He starred in the national company of Neil Simon's "The Last of the Red Hot Lovers", followed by the Broadway production of Simon's "California Suite". Next came "Cheaters" and "Break a Leg" with Julie Harris (I). Weston received a Tony nomination for his role in Woody Allen's "The Floating Light Bulb." Weston made his big-screen debut in Stage Struck (1958), starring Henry Fonda, and has had an active acting career spanning more than 30 years and at least 25 films. His first major film role was in Please Don't Eat the Daisies (1960) starring Doris Day (I) and David Niven (I). His film career became firmly established as he appeared with Steve McQueen (I) in Thomas Crown Affair, The (1968), Cincinnati Kid, The (1965) and Honeymoon Machine, The (1961). He worked with Ingrid Bergman (I) in Cactus Flower (1969), Audrey Hepburn in Wait Until Dark (1967) and Burt Reynolds (I) in several films including Fuzz (1972) and Gator (1976). He appeared in New Leaf, A (1971)--Elaine May (I)'s directorial debut--and worked for her again in Ishtar (1987). Weston has said that his favorite movie was Four Seasons, The (1981), written and directed by Alan Alda. He did his first TV series - "Rod Brown of the Rocket Rangers" (1953) - during "The Golden Age of Television" when the shows were shot live. He worked on "United States Steel Hour, The" (1953), "Playhouse 90" (1956), "Twilight Zone, The" (1959), "Bob Hope Presents the Chrysler Theatre" (1963), "Gunsmoke" (1955) and "Untouchables, The" (1959), as well as a comedy-drama special with Lucille Ball and Bob Hope (I). He later performed in the BBC-TV production of Roald Dahl's "Tales of the Unexpected" and the TV miniseries "Harold Robbins' 79 Park Avenue" (1977) (mini).
