Lois is a common English name from the New Testament. Paul the Apostle mentions Lois, the pious grandmother of Saint Timothy in the Second Epistle to Timothy (commending her for her faith in 2 Timothy 1:5). 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.
