Elmet (Welsh: Elfed), sometimes Elmed or Elmete, was a Brythonic kingdom thought to have been an independent polity between the 4th century and sometime after the mid-7th century as part of the Hen Ogledd.

The people of Elmet survived as a distinctly recognised group for centuries after it was absorbed into Yorkshire in what later became the smaller area of the West Riding of Yorkshire, and now West Yorkshire, South Yorkshire and north Derbyshire.
