The Oyster River is a 4.1-mile-long (6.6 km) stream located in the state of Connecticut in New Haven County. It flows south through Orange and forms the boundary of West Haven and Orange and further downstream the boundary of West Haven and Milford. It empties into Long Island Sound, just south of Route 162 at Oyster River Point. Swans, box turtles and many other animals call this area home. The river has dealt with issues of flooding and pollution in recent years. In 2007, a movement was put together by local residents to gain aid from the local government to help with these issues.
