The Ashburnham Center Historic District is a historic district in Ashburnham, Massachusetts in the United States. Development of its town center was only modest until the industrial period of 1830-1855, when industrial development along Phillips Brook spurred significant growth. This resulted in the construction of a significant number of Greek Revival houses, many of which survive in some form. In the second half of the 19th century, residential growth was modest, but a number of notable civic buildings were built, including a Methodist (later Roman Catholic) church in 1870, the Stevens Library (1890), and Town Hall (1904).
