The Deceangli or Deceangi (Welsh: Tegeingl) were one of the Celtic tribes living in Britain, prior to the Roman invasion of the island. The tribe lived in the region near the modern city of Chester but it is uncertain whether their territory covered only the modern counties of Flintshire, Denbighshire and the adjacent part of Cheshire or whether it extended further west. They lived in hill forts running in a chain through the Clwydian Range and their tribal capital was Canovium.
