USL Division One is the tentative name for a proposed professional men's soccer league in the highest level of the United States league system, alongside Major League Soccer. Organized by the United Soccer League (USL), it would supersede the USL Championship as its premier league for men, and would employ a promotion and relegation system with the Championship.
