Elbridge Boyden (1810–1898) was a prominent 19th-century American architect from Worcester, Massachusetts, who designed numerous civil and public buildings throughout New England and other parts of the United States. Perhaps his best known works are the Taunton State Hospital (1851) and Mechanics Hall (1855) in Worcester.

Taunton State Hospital is a psychiatric hospital located on Hodges Avenue in Taunton, Massachusetts. Established in 1854, it was originally known as the State Lunatic Hospital at Taunton. It was the second state asylum in Massachusetts. Most of the original part of the facility was built in a unique and rare neo-classical style designed by architects Boyden & Ball. It is also a Kirkbride Plan hospital and is located on a large 154-acre (62 ha) farm along the Mill River.
