Ioan Missir (February 17, 1890 – November 30, 1945) was a Romanian lawyer, politician and novelist. Born in the United States, he was raised in his father's native country from early childhood. There, he took part in World War I as an officer, worked as a lawyer and rose in local politics to become mayor. Missir's wartime experience informed his only novel, the 1937 Fata Moartă, which proved a resounding critical and commercial success.
