Aleijadinho (b. Antônio Francisco Lisboa; 1730 or 1738 – November 18, 1814) was a Colonial Brazil-born sculptor and architect, noted for his works on and in various churches of Brazil.

Born in Vila Rica (Rich Town), whose name was later changed to Ouro Preto (Black Gold), Minas Gerais, Brazil, in 1738 (sometimes said to be in 1730) he was the son of Manuel Francisco de Costa Lisboa, a Portuguese man and his African slave, Isabel. His father, a carpenter, had immigrated to Brazil where his skills were so in demand that he appears to have been elevated to the position of architect. When Antonio was young his father married and he was raised in his father's home along with his half siblings. It was there he is presumed to have learned the fundamentals of sculpture, architecture and the combination of the two. Antonio first appears as a day laborer working on the Church of Our Lady of Carmel in the town of Ouro Preto, a church designed by his father.

Within a very short time he had become a noted architect himself and had designed and constructed the Chapel of the Third Order of St. Francis of Assisi in Ouro Preto. He had also executed the carvings on the building, the most notable being a round bas-relief depicting St. Francis receiving the stigmata.
