Roy is a masculine given name and a family surname with varied origin. In Anglo-Norman England, the name derived from the Norman roy, meaning "king", while its Old French cognate, rey or roy (modern roi), likewise gave rise to Roy as a variant in the Francophone world. In India, Roy is a variant of the surname Rai , likewise meaning "king". It also arose independently in Scotland, an anglicisation from the Scottish Gaelic nickname ruadh, meaning "red".
