Homer of Colophon was a Greek epic poet from the 7th century BCE, active around 650–600 BCE. He came from the city of Colophon in Asia Minor and is often called "Homer the Younger" to distinguish him from the more famous Homer, author of the Iliad and Odyssey. Ancient sources record that he was the son of a poetess named Myro and was a pupil of another epic poet, Creophylus. Beyond these details, his life is largely unknown.

He is primarily associated with one work, a comic epic poem called the Margites. This poem is now lost and survives only in fragments and descriptions. According to ancient authorities like Aristotle, the Margites was significant as an early forerunner to comedy, featuring a foolish anti-hero who did everything badly. Other poems, such as the Battle of the Frogs and Mice and various hymns and foundation stories, were also attributed to him in later antiquity. Modern scholars, however, consider these other attributions to be spurious, likely added to his name because of its association with the legendary Homer.

His historical importance rests almost entirely on the Margites. Aristotle cited it as evidence that Homeric tradition helped inspire comic poetry, not just tragedy. The poem represents an interesting link in literary history between heroic epic and later comic genres. His legacy also illustrates a common ancient practice: multiple works were often attributed to a famous name, requiring later scholars to separate the different authors who bore it.
