Mick Bower will try to win the Rotherham parliamentary seat for the Yorkshire Party.
Mr Bower, who was born in the town, is a former teacher who has also worked in sports journalism and road safety.
He stood for election to Rotherham Council in May last year for the party then known as Yorkshire First, beating a Labour candidate but ultimately failing to win a seat in the Sitwell ward.
Mr Bower is on the steering group of the Yorkshire Party, which calls for a Yorkshire Assembly so decisions affecting the region can be made locally.
He said: "For decades, Labour have taken the people of Rotherham for granted and given them nothing in return. Our town's lost its soul. It's time for action."
“We can make Rotherham a place to be proud of again- an example to be followed by others. It will take the same guts and determination of the strong men and women who built this town. I'm ready for the challenge."
Mr Bower will attempt to unseat Labour's Sarah Champion.
