The Pere Marquette Railway (reporting mark PM) operated in the Great Lakes region of the United States and southern parts of Ontario in Canada. It had trackage in the states of Michigan, Ohio, Indiana and the Canadian province of Ontario. Its primary connections included Buffalo; Toledo; and Chicago. The company was named after Père (French for Father) Jacques Marquette S.J. (1637–1675), a French Jesuit missionary who founded Michigan's first European settlement, Sault Ste Marie.
