Nabil Ayouch (born 1 April 1969) is a Franco-Moroccan television and film director, producer, and writer. His films have screened at international film festivals including the Cannes Film Festival and Montreal World Film Festival.

Ayouch was born in 1969 in Paris, to a Moroccan father, Noureddine Ayouch and a French mother of Tunisian-Jewish descent. His brother is fellow director Hicham Ayouch. After his parents' divorce, he spent a large part of his childhood in the suburb of Sarcelles, visiting Casablanca in the summers.

Ayouch cites discovering international cinema at the local cultural center, Forum des Cholettes, as inspiring his filmmaking career.

Ayouch started his career as a scriptwriter and director with the advertising agency Euro-RSCG. In 1992, he directed Les Pierres bleues du désert, a first short film with Jamel Debbouze which tells the history of a young man convinced that there are large blue stones in the desert.

In 1993, Ayourch ended up settling in Casablanca, where he directed two short films, Hertzienne Connexion (1993) and Vendeur de silence (1994), for which he received international recognition.

In 1997, Ayouch directed his first feature film Mektoub, which represented Morocco at the Oscars. He also directed the feature films Une Minute de soleil en moins (2003) and Whatever Lola Wants (2008), produced by Pathé.

In 1999, Ayouch created a production company called Ali n'Productions to aid aspiring young directors in establishing their careers. He won the Ecumenical Award in 2000 in the Montreal World Film Festival for his film Ali Zaoua: Prince of the Streets. Ayouch is set to produce the French-Moroccan thriller film Mirages.

Ayouch's 2012 film Horses of God is based on Mahi Binebine’s novel The Stars of Sidi Moumen. In Horses of God, Ayouch explores the radicalization that can occur from poverty and extreme machismo, alluding to the 2003 Casablanca bombings. The film competed in the Un Certain Regard section at the 2012 Cannes Film Festival. It was also Morocco's submission for the 85th Academy Awards (held in February 2013).

In 2021, Ayouch's film Casablanca Beats was selected for the 74th Cannes Film Festival competition.
