The Church of Saints Cosme and Damião (Portuguese: Igreja dos Santos Cosme e Damião), officially called the Igreja Matriz de São Cosme e São Damião, is a Catholic church located in the city of Igarassu, Pernambuco. The church dates to 1535, early in the settlement of Pernambuco, and survived the Dutch invasion of the 17th century. It is the oldest functioning church in Brazil, according to the Brazilian National Institute of Historic and Artistic Heritage. The church is part of the Roman Catholic Archdiocese of Olinda and Recife and sits adjacent to the Church and Convent of Saint Antony, now a museum.
