Napoleon Lapathiotis (31 October 1888 – 7 January 1944) was a Greek poet. A native of Athens, he began writing and publishing poetry when he was eleven. In 1907, along with others, he established the Igiso (Ἡγησώ, from the Attic Greek name Hēgēso) magazine, in which he published his works. In 1909, he graduated from the law school of the University of Athens. His first book of poems was published in 1939.
Lapathiotis was openly gay and had communist beliefs. Poor in later life and an opium addict, he committed suicide with a revolver on 7 January 1944.
The 1985 film Meteor and Shadow was based on his life.
