Janis Siegel (born July 23, 1952) is a multiple grammy-winning American jazz singer, best known as a member of the vocal group The Manhattan Transfer.

After one single, "The Hideaway", the group disbanded, and then Siegel went on to join the folk trio The Loved Ones (later Laurel Canyon).

In 1972, after the original Manhattan Transfer had disbanded, founder Tim Hauser met Siegel at a party.

This incarnation of the group has enjoyed international popularity, covering songs from the 1930s through the 1980s in a variety of genres including jazz fusion, R&B, pop, and doo wop.
