John Wick (retroactively known as John Wick: Chapter 1) is a 2014 American neo-noir action-thriller film directed by Chad Stahelski, in his directorial debut, and written by Derek Kolstad. It stars Keanu Reeves, Michael Nyqvist, Alfie Allen, Adrianne Palicki, Bridget Moynahan, Dean Winters, Ian McShane, John Leguizamo, and Willem Dafoe. It is the first installment in the John Wick film series.

The story focuses on John Wick (Reeves) searching for the men who broke into his home, stole his vintage car and killed his puppy, which was a last gift to him from his recently deceased wife. Chad Stahelski and David Leitch directed the film together, though only Stahelski was credited.

Kolstad had completed the screenplay in 2012 and further developed it for Thunder Road Pictures. The film was produced by Basil Iwanyk of Thunder Road Pictures, Leitch, Eva Longoria, and Michael Witherill. It marks Stahelski and Leitch's directorial debut as a team after multiple separate credits as second-unit directors and stunt coordinators. They previously worked with Reeves as stunt doubles on The Matrix trilogy.

Stahelski and Leitch's approach to fight scenes drew upon their admiration for anime and martial arts films. The film used fight choreographers and gun fu techniques from Hong Kong action cinema. The film also pays homage to works such as John Woo's The Killer, Jean-Pierre Melville's Le Cercle Rouge and Le Samouraï, John Boorman's Point Blank, and the Spaghetti Western films.

The film was met with positive reviews, with critics labeling it as one of Reeves' best performances and one of the best action films of 2014. It grossed $86 million worldwide against a production budget of $20–30 million. Two sequels, John Wick: Chapter 2, and John Wick: Chapter 3 – Parabellum, released in 2017 and May 2019 respectively, both met with comparable critical and commercial success, with another sequel, John Wick: Chapter 4, set for a May 2022 release and an untitled fifth film following that.
