Baron of Alagoa (Portuguese: Barão de Alagoa) was a noble title created by Queen Maria II of Portugal by decree on 22 December 1841 in favor of José Francisco da Terra Brum, a wealthy merchant and winegrower from the city of Horta, Faial Island, in the Portuguese archipelago of the Azores. Terra Brum resided along the banks of the Ribeira da Conceição (literally, the Stream of the Immaculate Conception), and owned properties on the so-called Alagoa coastline. Today, the latter area is occupied by the football field of local sports club Fayal Sport.
