Utopia is a work of fiction and socio-political satire by Thomas More (1478–1535), written in Latin and published in 1516. The book is a frame narrative primarily depicting a fictional island society and its religious, social and political customs. Many aspects of More's description of Utopia are reminiscent of life in monasteries.

The title De optimo rei publicae statu deque nova insula Utopia literally translates, "Of a republic's best state and of the new island Utopia".
