The Second O'Shea Building is a historic commercial building at 9-13 Peabody Square in Peabody, Massachusetts. It is one of two similar buildings (see O'Shea Building for the other) built by Thomas O'Shea, a local leathermaker, in the 1900s. The three story brick and sandstone Colonial Revival building occupies a prominent position in Peabody Square, the city's central intersection. Similarities to the earlier building include the arched entrances and window bays, and the brick pilasters (with limestone bases and capitals) between some of the window bays.
