Benjamin S. Deane (1790–1867) was an American master builder and architect in practice in Bangor, Maine, from c. 1832 to 1867.
He quickly became locally successful, and in 1835 was chosen builder of St. John's Episcopal Church, an important early work of architect Richard Upjohn.
[3] During the early 1850s he was assisted in his office by Edwin Lee Brown, later an architect in Boston and New York City.
[8] Deane's First Baptist Church at Sedgwick, built in 1837, has been identified by former National Park Service architectural historian Denys Peter Myers as "one of the finest and most suavely designed wooden Greek Revival churches in New England."
In this and other works Deane borrowed from pattern books, including those of Asher Benjamin.
