Sant Joan de Labritja (Catalan pronunciation: [ˈsaɲ ʒuˈan də ləˈβɾidʒə], Spanish: San Juan Bautista) is a village and municipality of the Balearic Islands on northern Ibiza.

One may find several small cafés and restaurants (including the locally well-known Vista Alegre, as well as a taxi rank, outside the Municipal Council building and the local office of the Guardia Civil, the Spanish Civil Guard.

Towards the west of the village is the origin of the Torrent de Labritja, a tributary of the Riu de Santa Eulária, the Balearic Island's only constant-flowing river, although the Torrent only contains water during the winter months; throughout the tourist season, the stream is a dry river bed full of green vegetation.

For many years, especially throughout much of the 20th century, the municipality was known by its Spanish name, San Juan Bautista.

The village of Portinatx on the northern coast is the only major tourist resort as well as the western port of Sant Miquel (San Miguel).
