The Baldwin River is a left tributary of the River Glass on the Isle of Man. It is about 6 km long. It rises near Beinn-y-Phott (and near Brandywell Corner on the TT Course) and flows southwards through the East Baldwin valley to join the Glass about 4 km east of Crosby and just over a mile (or just under 2 km) north of Noble's Hospital, Douglas. For much of its course it forms the parish boundary between Braddan (to the west) and Onchan (to the east).[1]
