Debra Jo Rupp (born February 24, 1951) is an American television actress perhaps best known for her role as Kitty Forman on the long-running FOX sitcom That '70s Show.

The television series Friends made use of Rupp's comedic talents in several episodes, beginning in 1997 and continuing through 1998. On the show, she played Alice Knight, a home economics teacher who fell in love with and married the much younger Frank Jr. (Giovanni Ribisi), Phoebe Buffay's half-brother. Her memorable performances on Friends earned her notice at the casting department of That '70s Show.
