The Church and Convent of Saint Antony (Portuguese: Igreja e Convento de Santo António) is a 17th-century Roman Catholic church located in Cairu, Bahia, Brazil. It was consecrated in 1650, but construction on the complex probably began at the beginning of the century. The church building is noted for its elaborate façade and numerous Franciscan architectural elements. It covers 3,215 square metres (34,610 sq ft). The church was listed as a historic structure by the National Historic and Artistic Heritage Institute in 1941. The architect Mário Mendonça de Oliveira calls the convent and church "one of the most outstanding existing examples of Brazilian religious architecture and Franciscan architecture."
