Lewis (/ˈluːɪs/) is a masculine English-language given name. It was coined as an anglicisation of given names in other languages.
"Lewis" has been used to anglicise the Irish name "Lugaid", the German name "Ludwig", and the French name "Louis" (the last two originally deriving from the Old Frankish name Chlodowig). It may also be a borrowing from the Isle of Lewis in the Outer Hebrides, whose name derives from the Scottish Gaelic Leòdhas.
