The town was created in 2001, amalgamating the township of Plympton with the formerly independent village of Wyoming. The town's first mayor was Patricia Davidson, who was elected to the Canadian House of Commons in the 2006 federal election as the Conservative Member of Parliament for Sarnia—Lambton. Davidson also served as mayor of the village of Wyoming for ten years prior to her election as mayor of the amalgamated town. Davidson was succeeded as mayor by former town councillor and deputy mayor Lonny Napper in March 2006. The township is governed by a seven-member Council, including a Mayor and Deputy Mayor. 
The name Wyoming derives from the Munsee name xwé:wamənk, meaning "at the big river flat."
