Lois is a common English name from the New Testament.

The name was first used by English Christians after the Protestant Reformation, and it was popular, particularly in North America, during the first half of the 20th century.

In French, Loïs is a male name, as in the fictional comic strip adventures of Loïs Lorcey by Jacques Martin.

[citation needed] The name Loïs is derived from the name Louis, itself derived from Clovis which is derived from the Germanic root, Hlodowig, which can be interpreted in the sense of "glorious" or "illustrious fighter".
