The Equalizer is a 2014 American vigilante action film directed by Antoine Fuqua, loosely based on the 1980s TV series of the same name. Written by Richard Wenk, it stars Denzel Washington in the lead role, Marton Csokas, Chloë Grace Moretz, David Harbour, Bill Pullman and Melissa Leo. The film focuses on a former U.S. Marine turned DIA intelligence officer who reluctantly returns to action to protect a teenage prostitute from members of the Russian mafia. Principal photography began in June 2013 in Massachusetts.

The Equalizer had its world premiere at 2014 Toronto International Film Festival on September 7, 2014, and was released worldwide on September 26, 2014, in conventional and IMAX theaters. It received mixed reviews from critics, who praised the visual style, direction, acting, soundtrack, and action sequences but criticized its depictions of violence and plot. Nonetheless, it became a commercial success with a worldwide gross of over $192 million on a production budget of $55–73 million.

A sequel was released on July 20, 2018, with Denzel Washington, Richard Wenk, and Antoine Fuqua returning. A third film is in the works with Washington reprising his role and Fuqua returning to direct.
