The Lorraine Open is a defunct men's tennis tournament that was played as part of the Grand Prix tennis circuit from 1979 to 1989. It was held in Lorraine, one of the 26 regions of France. The venue alternated annually from Lorraine's two main cities of Metz and Nancy, with Nancy hosting odd-numbered years, and Metz even-numbered. The surface in both locations was indoor carpet courts.^[1]
