United Streetcar, LLC, was an American manufacturer of modern streetcars, located in the Clackamas area in the southeastern suburbs of Portland, Oregon, founded in 2005. It was the only U.S. company building modern streetcars—as distinct from light rail cars or new replicas of historic streetcars—until 2013, when Brookville received its first order for a modern (as opposed to faux historic) streetcar, for the Dallas Streetcar.
