Jayne Meadows, a glamorous redheaded actress who starred on Broadway, in the movies and on television, but who was probably best known for her 46-year role as Steve Allen’s wife, business partner and frequent co-star, died on Sunday at her home in Encino, Calif. She was 95.

Her son, Bill Allen, confirmed her death on Monday.

Ms. Meadows was never as well known as her younger sister, Audrey, who played Alice Kramden on the now-classic Jackie Gleason sitcom “The Honeymooners.” But she was a versatile and accomplished actress in her own right and a familiar presence on television for years, in dramatic productions, prime-time series and game shows.

She was born Jayne Meadows Cotter on Sept. 27, 1919, in Wuchang, China, where her father, Francis James Meadows Cotter, and her mother, the former Ida Miller Taylor, were Episcopal missionaries. The family moved back to the United States in 1927, and her father eventually became rector of Christ Church in Sharon, Conn. After attending a girls’ boarding school with her sister, she went to New York to be an actress.

Ms. Meadows made her Broadway debut in 1941 in the comedy “Spring Again.” Her other Broadway appearances included “Another Love Story” (1943); “Many Happy Returns” (1945), with Mary Astor; and “Kiss Them for Me” (1945), in which she was featured with Richard Widmark.
