Matteo Castelli (c. 1555, Melide, Switzerland - 1632, Warsaw) was a Swiss architect. His nephew Costante Tencalla also became an architect. Further can be attributed to Castelli: in Kraków the church of St. Peter and Paul (1613–1619, the only church north of the Alps in the Roman Baroque style), the Zbaraski princely chapel in the Dominican church (1627-1629) and the altar of St. Stanislaus in the cathedral, also in Vilnius cathedral the chapel of St. Casimir (1626–1636), the Ujazdowski palace and the royal residence near Warsaw. In Melide he donated a memorial chapel in 1625-1626 and rebuilt the altar of his family in the parish church.
