St. Francis Xavier Church is a Catholic church within the City of Winooski, Vermont in the United States. Built in 1870 within what was then known as a village within the township of Colchester, the parish church became one of the most visible landmarks in Chittenden County due to its unique double-spired design and proportional size comparative to its surrounding structures. The Church was listed on the Vermont State Historic Register on November 22, 1993.
