Nina Foch (; born Nina Consuelo Maud Fock; April 20, 1924 – December 5, 2008) was a Dutch American actress. After signing a contract with Columbia Pictures at age 19, Foch became a regular in the studio's horror pictures and films noir before establishing herself as a leading lady in the mid-1940s through the 1950s, often playing roles as cool, aloof sophisticates. Her career spanned six decades, consisting of over 50 feature films and over 100 television appearances.

She is perhaps best known for her roles in An American in Paris (1951); Robert Wise's Executive Suite (1954), which earned her an Academy Award nomination for Best Supporting Actress; Cecil B. DeMille's The Ten Commandments (1956); and Stanley Kubrick's Spartacus (1960).

Foch also worked extensively in television, making a multitude of appearances from 1951 until 2007. In addition to acting, Foch taught drama at the American Film Institute and at the University of Southern California's School of Cinematic Arts, where she was a faculty member for over 40 years until her death in 2008.
