The Plough and Stars is a bar and music venue in Cambridge, Massachusetts. It was founded in 1969 by brothers Padraig and Peter O'Malley, named after the play by Seán O'Casey. The Boston Globe and Boston Phoenix have noted its disproportionate cultural influence for its size, with a number of noted musicians, writers, and politicians frequenting the bar over the years.
The literary journal Ploughshares is named for the bar, where it was founded in 1971 by DeWitt Henry and former bartender/owner Peter O'Malley.
