Sa Font (Cabrera Island, Balearic Islands, Spain) is a site in which important human activity has been documented from the 5th century to the 13th century, related to a monastic community from the 5th to 8th centuries and a possible Islamic farmhouse from the 10th to the 13th centuries.

It is the place where the most important freshwater spring on the island is located (currently it is a qanat). The presence of terraces stands out, both for irrigated and dryland agriculture.

A short distance away, the monastery of the monastic community has been documented, with valuable contexts very well dated from the 5th, 6th, 7th and 8th centuries, with abundant fauna, many charcoals and some burials.
