Louis Nowra (born 12 December 1950) is an Australian writer, playwright, screenwriter and librettist.
His most significant plays are Cosė, Byzantine Flowers, Summer of the Aliens, Radiance, and The Golden Age, which has been cited as a good example of Tasmanian Gothic fiction. In 2007 he completed The Boyce Trilogy for Griffin Theatre Company, consisting of The Woman with Dog's Eyes, The Marvellous Boy and The Emperor of Sydney. A number of his plays have been turned into films.
Nowra was born Mark Doyle in Melbourne. He changed his name to Louis Nowra in the early 1970s. He studied at Melbourne's La Trobe University without earning a degree. In his memoir, The Twelfth of Never, Nowra claimed that he left the course due to a conflict with his professor over Patrick White's The Tree of Man. He worked in several jobs and lived an itinerant lifestyle until the mid-1970s, when his plays began to attract attention.
His radio plays include Albert Names Edward, The Song Room, The Widows and the five part The Divine Hammer aired on the ABC in 2003.
In March 2007, Nowra published a controversial book on violence in Aboriginal communities, Bad Dreaming.
Nowra has been studied extensively in Veronica Kelly's work The Theatre of Louis Nowra. He resides in Sydney with his wife, author Mandy Sayer.
