Walter Joseph Boasso (born May 10, 1960) is an American businessman and Democratic former state senator from Chalmette, the seat of government of St. Bernard Parish in south Louisiana. He was defeated in a bid for governor in the October 20, 2007, nonpartisan blanket primary by the Republican Bobby Jindal. Boasso won 47 percent in his own St. Bernard Parish, his sole plurality showing in any of his state's sixty-four parishes. From 2004 to 2008, Boasso represented Senate District 1, which includes parts of Orleans, Plaquemines, St. Bernard, and St. Tammany parishes, many of those areas having been devastated by Hurricane Katrina.
