Sir Ralph Bulmer (died 1558) of Wilton in Yorkshire (present day Redcar and Cleveland), was an English knight and soldier active on the Scottish border and during the war of the Rough Wooing.
Around 1535, Ralph married either Anne Aske, a co-heiress of Roger de Aske, or Anne Tempest a daughter of Sir John Tempest. Henry VIII granted them possessions of Marrick Priory.
