The Fajã de João Dias is a permanent debris field, built from the collapsing cliffs on the northern coast of the civil parish of Rosais, in the municipality of Velas, island of São Jorge, in the Portuguese archipelago of the Azores.

The remainder of the buildings became weekend retreats and for those with plots of land used to cultivate figs, vines and corn; these residents living elsewhere on the island.

The settlement is inaccessible by vehicle or along the coast, but a paved road down the cliff was under construction in the east, by 2009.

This trail is accessible by foot or pack animal, and snakes down the 450 metres (1,480 ft) cliff.

Freshwater is supplied from springs along the cliff, while most houses have cisterns to collect water in the settlement.
