Norphlet was called Jesse in the 1880s. The Post Office was created in 1891. The town originally centered around William G. Miles's Sawmill. The town was named for Nauphlet Goodwin. The name of the town was misspelled by the Postal Department when the Post Office was created. The word, Nauphlet, was written in long hand and looked like Norphlet to the people in the Postal Department. So, the papers for the post office were issued for Norphlet. Oil was discovered at Norphlet in 1922. The formation in which the oil was discovered led to 'Norphlet' becoming a geological term - a Norphlet Formation is a Jurassic Sandstone Formation.
