Alcaucin (Spanish pronunciation: [alkawˈθin]) is a town and municipality in the province of Málaga, part of the autonomous community of Andalusia in southern Spain.

The weasel, bobcat, badger, and genet live in these in the areas with the highest density of trees.

Some authors hypothesize that the name was due to the existence of an aqueduct and others to the abundance of yew trees, whose wood is used for making hunting bows, which have the form of an arc.

During the period of Phoenician colonization, they laid the foundations of the fortress of Zalía, but it was the Arabs who built the present castle in 1485 until it was conquered by the Catholic Monarchs.

During the Andalusian earthquake of 25 December 1884, 134 houses in the municipality collapsed, 22 in the nucleus (6 dead and 5 seriously injured) and 112 in the surrounding area.
