The Arthur Provost Three-Decker is a historic triple decker house in Worcester, Massachusetts.

[1] The Arthur Provost Three-Decker is located southeast of downtown Worcester, on the south side of Thorne Street in the city's Franklin Plantation neighborhood.

It is a three-story structure, built out of red brick and covered by a hip roof.

The right side originally had a stack of wooden porches with elaborate Queen Anne styling, including turned posts, spindled balusters, and bracketed eaves;[2] the porches have subsequently been entirely removed, and the upper-floor doorways filled by wood framing and windows, while the ground-floor entrance is now fronted by an open porch with iron railing.

Its first known owner, Arthur Provost, was a bookkeeper, and many of its early tenants were of French Canadian extraction.
