The River Rye or Ryewater (Irish: Abhainn na Rí) is a tributary of the River Liffey. It rises in County Meath, flowing south-east for 19 miles. Although the river has been the subject of arterial drainage schemes, it is generally fast flowing over a stoney bottom. The Rye's major tributary is the Lyreen.
