Hermione Ferdinanda Gingold (; 9 December 1897 – 24 May 1987) was an English actress known for her sharp-tongued, eccentric character.

Her signature drawling, deep voice was a result of nodules on her vocal cords she developed in the 1920s and early 1930s.

After a successful career as a child actress, she established herself on the stage as an adult, playing in comedy, drama and experimental theatre, and radio broadcasting. She found her milieu in revue, which she played from the 1930s to the 1950s, co-starring several times with the English actress Hermione Baddeley. Later she played formidable elderly characters in films and stage musicals such as Gigi (1958), Bell, Book and Candle (1958), The Music Man (1962) and A Little Night Music (1977).

From the early 1950s, Gingold lived and made her career mostly in the U.S. Her American stage work ranged from John Murray Anderson's Almanac (1953) to Oh Dad, Poor Dad, Mamma's Hung You in the Closet and I'm Feelin' So Sad (1963), the latter of which she played in London. She became a well-known guest on television talk shows. She made appearances in revues and toured in plays and musicals until an accident ended her performing career in 1977.
