Fort Jesus is a Portuguese fort built in 1593 on Mombasa Island to guard the Old Port of Mombasa, Kenya. It is built in the shape of a man, and was given the name of Jesus in an obvious religious reference.

Between 1631 and 1875 the fort was won and lost nine times by the nations contesting control of Mombasa. It was declared a historical monument in 1958. Today it houses a museum.
