St. Mary of the Assumption Church (commonly referred to as St. Mary's) is a parish of the Roman Catholic Church in Dedham, Massachusetts, in the Archdiocese of Boston.
The first church was constructed in Dedham Centre in 1857 and it was formally established as a parish in 1866. In 1880 the parish built a larger church on High Street, towards East Dedham. The laying of the cornerstone for this "cathedral in the wilderness" attracted more than 4,000 people, and special trains were run from Boston and Norwood. The new church would not be completed until 1900, and was dedicated by Archbishop Sebastiano Martinelli, the papal delegate. Today the church hosts one of the largest Life Teen programs in the country.
