The Brown Square House, now the Garrison Inn, is a historic pair of rowhouses at 11 Brown Square in Newburyport, Massachusetts. The four story brick rowhouses were built in 1809 and 1810 by Moses Brown, a Newburyport landowner, shipbuilder, and shipping merchant. Brown had planned to build a much longer row, but suffered financial reverses and was unable to build more than the pair. Sometime before 1849 the building was adapted for use as a boarding house. In 1922 it was turned into a hotel, named in honor of abolitionist William Lloyd Garrison, a statue of whom graces the square. That hotel closed in 1948, but the building has since been rehabilitated and reopened under the same name.
