June Allyson (born Eleanor Geisman; October 7, 1917 – July 8, 2006) was an American stage, film, and television actress, dancer, and singer.

Allyson began her career in 1937 as a dancer in short subject films and on Broadway in 1938. She signed with MGM in 1943, and rose to fame the following year in Two Girls and a Sailor. Allyson's "girl next door" image was solidified during the mid-1940s when she was paired with actor Van Johnson in six films. In 1951, she won the Golden Globe Award for Best Actress for her performance in Too Young to Kiss. From 1959 to 1961, she hosted and occasionally starred in her own anthology series, The DuPont Show with June Allyson, which aired on CBS from 1959 to 1961.

In the 1970s, she returned to the stage starring in Forty Carats and No, No, Nanette. In 1982, Allyson released her autobiography June Allyson by June Allyson, and continued her career with guest starring roles on television and occasional film appearances. She later established the June Allyson Foundation for Public Awareness and Medical Research and worked to raise money for research for urological and gynecological diseases affecting senior citizens. During the 1980s, Allyson also became a spokesperson for Depend undergarments, in a successful marketing campaign that has been credited in reducing the social stigma of incontinence. She made her final onscreen appearance in 2001.

Allyson was married four times (to three husbands) and had two children with her first husband, Dick Powell. She died of respiratory failure and bronchitis in July 2006 at the age of 88.
