Eberhard of Béthune (also known as Everard of Béthune, Évrard de Béthune, Éverard de Béthune, Ebrardus Bethuniensis or Bithuniensis, Eberhardus Bethuniensis, Eberard, Ebrard, Ebrad; d. c. 1212) was a Flemish grammarian of the early thirteenth century, from Arras. He was the author of Graecismus, a popular Latin grammatical poem, dated to c. 1212. The name came from a short section on the Greek language. His Laborintus is "an elaborate and critical treatise on poetry and pedagogics"; it is also known as De Miseriis Rectorum Scholarum. He was also actively engaged against the Waldensians, and wrote a book Liber Antihaeresis (c 1210) against them. He is cited in Foxe's Book of Martyrs as to the etymology of the name.
