"Waldere" or "Waldhere" is the conventional title given to two Old English fragments, of around 32 and 31 lines, from a lost epic poem, discovered in 1860 by E. C. Werlauff, Librarian, in the Danish Royal Library at Copenhagen, where it is still preserved. The parchment pages had been reused as stiffening in the binding of an Elizabethan prayer book, which had presumably come to Europe following the Dissolution of the Monasteries in England in the 16th century.
