The War of Don Emmanuel's Nether Parts is a novel by Louis de Bernières, first published in 1990. It is the first of his Latin American trilogy. The other two parts are Señor Vivo and the Coca Lord and The Troublesome Offspring of Cardinal Guzman.
It is de Bernières' first published novel, but is an accomplished and complex work. His recognition of evil is combined with sympathy for those characters trapped in evil patterns of behaviour, a characteristic of his later work which is perhaps more pronounced in this early work than in his greatest hit Captain Corelli's Mandolin.
