The Patrick McGuinness Three-Decker is a historic triple decker at 25 Suffield Street in Worcester, Massachusetts. It was built c. 1908, and is a rare well-preserved example of a double triple-decker (housing six units) with Colonial Revival styling. The building has a central recessed porch area where each level has a slightly different treatment: the first level has full-length turned columns, the second level has half-height columns above a shingled balustrade, and the third level has arch-forming brackets resting on short piers. The bays flanking the porch area are rounded.
