José Maria de Santo Agostinho, born Miguel Boaventura Lucena (died 22 October 1912), was a Brazilian religious leader from the state of Santa Catarina.

He was the third of three monks named João Maria who appeared in turn in southern Brazil, preaching and healing with herbs.

He resurrected a young woman thought to be dead and cured the wife of a colonel of a disease that the doctors had proclaimed uncurable.

[2] He was the religious leader of the rebels during the "Contestado War" of 1912–16, in which small farmers and settlers in Paraná and Santa Catarina who had been expelled from their lands fought against the large capitalist landowners and companies.

[3] He gathered a following in the Contestado, a region between Parana and Santa Catarina, opposed to construction of a railway that would open the land to outsiders.
