The Pleasant Street Congregational Church is an historic Congregational church at 75 Pleasant Street in Arlington, Massachusetts. The church was built in 1844 for a congregation that split doctrinally from the First Parish Church, whose adherents chose to become Unitarian. The church is a fine example of pattern-book Greek Revival architecture. Its steeple was toppled in 1871, and was again damaged by the New England Hurricane of 1938, necessitating steel reinforcements. The interior was restyled in the late Victorian period, and lengthened in 1883 to accommodate increased attendance. The Colonial Revival front entrance dates to the a series of alterations and repairs made after the 1938 hurricane.
