Hobday is an English surname chiefly found in the West Midlands. It derives from Hob, a medieval short form of the male given name Robert, combined with the Middle English word day, meaning "servant."" The full meaning of the surname could thus be interpreted as either "Hob the servant" or "servant of Hob."
