San Alejo is a municipality in the La Unión department of El Salvador.

A mid-eighteenth century, in the parish of Conchagua, there was the San Alejo de Pedregal, rocky site known as Queiquín native Lenca. These natives had yayantiques neighbors as its rivals. Shortly after a brawl that took place in 1771 among such enemies, the Supreme Head of the Province of San Miguel ordered to organize a village in the land donated by the owners of the property. With the creation of the Municipality of San Salvador in 1785, the town went on to become the capital of one of the fifteen games.
