Diva (Korean: 디바, romanized: Diba) is a 2020 Korean thriller film directed by Cho Seul-ye, starring Shin Min-a and Lee Yoo-young. The film marks the directorial debut of Cho Seul-ye and revolves around a competitive diver (Shin Min-a) and her best friend and rival (Lee Yoo-young), who goes missing after the two are involved in a car accident. It was released in Korea on September 23, 2020.

The title of the film was suggested by director Park Chan-wook, who reviewed an early draft of the screenplay. Cho found that the word translated to "goddess" in Italian, but to "demon" in Arabic; she appreciated the dual meaning, and so adopted it as the title of her film.

The film received two nominations in the 41st Blue Dragon Film Awards: for Best Leading Actress (Shin); and for Best Cinematography and Lighting.
