Annunciation Greek Orthodox Church in Wauwatosa, Wisconsin, United States, was designed by architect Frank Lloyd Wright in 1956, and completed in 1961. It is listed on the National Register of Historic Places. The church is one of Wright's last works; construction was completed after his death. The design is informed by traditional Byzantine architectural forms, reinterpreted by Wright to suit the modern context.
