W. de Wycombe (fl. late 13th century; also Wicumbe, Whichbury and Winchecumbe) was an English composer of the high medieval music.[1] He was precentor of the priory of Leominster in Herefordshire. It is possible that he was the composer of one of the most famous tunes from medieval England, "Sumer is icumen in".[1]
