Thomas Weelkes (1576–1623) was an English composer and organist of the Renaissance period. He became organist of Winchester College in 1598, moving to Chichester Cathedral. His works are chiefly vocal, and include madrigals, anthems and services. Thomas Weelkes was baptised in the little village church of Elsted in Sussex on 25 October 1576. It has been suggested that his father was John Weeke, rector of Elsted, although there is no documentary evidence of the relationship.
