Treat Her Right was an American rock group, formed in Boston, Massachusetts, United States, in 1985. The band originally featured Mark Sandman on "low guitar", Billy Conway on cocktail drum, David Champagne on guitar and Jim Fitting on harmonica. Singing and songwriting duties were shared by all but Conway. Champagne and Fitting reformed the band in 2009 with new members Steve Mayone and Billy Beard.
Treat Her Right was the forerunner to the successful indie rock band Morphine. Critic Ira Robbins described Treat Her Right as "[n]ot quite a blues band, not exactly swamp trash and too stylized for basic rock'n'roll." The Rough Guide to Rock later used the label "punk-blues" to describe the band. However, "punk" was not a characteristic associated with the band while it was active.
Sandman stated the band's aesthetic: "Keep it simple at all costs. Resist the temptation to add. If you're going to do something to a song, subtract."
