Baldwin River (Isle of Man)

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 flows southwards through the East Baldwin valley to join the Glass about 4 km east of Crosby and just over a mile north of Noble's Hospital, Douglas. For much of its course it forms the parish boundary between Braddan and Onchan.
Its name in Manx Gaelic, from which the English version appears to be derived, is Awin Voaldyn, or Boaldyn before initial mutation, which corresponds to the festival of Beltane in May.
