Ek Hasina Thi (English: There Was A Beautiful Woman) is a 2004 Indian Hindi-language neo-noir action thriller film directed by Sriram Raghavan and produced by Ram Gopal Varma. It stars Urmila Matondkar and Saif Ali Khan, and the screenplay was written by Sriram Raghavan and Pooja Ladha Surti.

The film borrows elements from the Sidney Sheldon novel If Tomorrow Comes. Critic Ronjita Kulkarni said it's "loosely based" on Double Jeopardy, while "the film also adapts a scene from The Bone Collector." The film premiered at the New York Asian Film Festival. Although a commercial failure upon its release, the film is considered one of the best works of Matondkar, Khan and Raghavan.
