The name stems from the ancient province in France where the method of boring artesian wells was first adopted. Artois was formerly named Germantown, and petitions to change the Germantown post office name were successful with Artois adopted on May 21, 1918. Local belief is that a World War I troop train stopped to water at Gemantown and a riot ensued when the troops took offense at the name. The town was then renamed after the battles of Artois.
The Germantown post office opened in 1877, and changed its name to Artois in 1918.
