Dume is a former freguesia ("civil parish") and former bishopric in the municipality of Braga, northern Portugal, which remains a Catholic titular see.

Dume enjoyed in earlier times a relief situation especially in the sixth century during the reign of Theodemar king of the Suebi.

So remarkable became his action that in 558 it was elevated to the episcopal dignity, turning the church into a cathedral, the area of the monastery becoming the Bishopric of Dume.

The ancient parish of São Martinho de Dume was one resignation from the patronage of the presentation of the prelate of Braga.

At the place of Cabanas, there is a Manor house with a chapel, where on 25 December 1888, the resigning Archbishop of Braga Dom João Crisóstomo de Amorim Pessoa died.
