The Portuguese raids in Senegambia were a series of mid-15th century expeditions carried out by explorers and slave raiders in the service of Prince Henry of Portugal along the coasts of present-day Senegal and The Gambia.

Although these expeditions largely ended in failure, they marked the first steps in Portuguese expansion along the West African coast, a process that would eventually lead to its naval victory at Diu in 1509. At the same time, these encounters revealed the military organization and tactics of the Malian and Jolof empires, and that European naval superiority was limited.
