My Neighbor, My Killer (French: Mon voisin, mon tueur) is a 2009 French-American documentary film directed by Anne Aghion that focuses on the process of the Gacaca courts, a citizen-based justice system that was put into place in Rwanda after the 1994 genocide.

Filmed over ten years, it makes us reflect on how people can live together after such a traumatic experience.

Through the story and the words of the inhabitants of a small rural community, we see survivors and killers learn how to coexist.

It was an Official Selection at the 2009 Cannes Film Festival,[1] the winner of the Human Rights Watch's Nestor Almendros Prize[2] for courage in filmmaking, a nominee for the 2009 Gotham Best Documentary Award[3] and the winner of the best documentary at Montreal Black Festival.

[4] My Neighbor, My Killer is the feature length based on the Gacaca Series, composed of three films that Anne Aghion made over the years in Rwanda, one of which - "In Rwanda We Say…The Family That Does Not Speak Dies"[5] - received an Emmy Award.
