The Insatiable Moon is a 2010 New Zealand drama film, based on a 1997 novel of the same name by Mike Riddell, who also wrote the screenplay. The film was directed by Rosemary Riddell, and stars Rawiri Paratene in the leading role as Arthur, self-proclaimed second son of God. Arthur sets off on a mission to find the 'Queen of Heaven', and finds her in Margaret (Sara Wiseman), just as the community boarding house he calls home faces threat.

The film focuses on themes around mental illness and discrimination, and draws on Mike Riddell's experiences working with those with mental health problems and those that are underprivileged. This is what both the novel and screenplay are based on. The film was shot in Ponsonby, a suburb of Auckland.

The film has been screened at Mental Health events, such as Mental Health Awareness Week in 2013.
