U.S. Route 75 is a north–south U.S. Highway. The highway's northern terminus is in Noyes, Minnesota, at the Canada–US border, where it once continued as Manitoba Highway 75 on the other side of the now-closed border crossing. Its southern terminus is at Interstate 30 and Interstate 45 in Dallas, where it is known as North Central Expressway.

U.S. 75 was a border-to-border route, from Canada to the Gulf of Mexico at Galveston, Texas. However, the entire segment south of Dallas has been decommissioned in favor of Interstate 45, a cutoff section of town-to-town surface road having become State Highway 75.

The first freeway in Texas was a several-mile stretch of US 75 (now I-45)--The Gulf Freeway, opened to Houston traffic on October 1, 1948. The stretch of US 75 between Interstate 30 and the Oklahoma state line has exits numbered consecutively from 1 to 75 (with occasional A and B designations), excluding 9-19. All other Texas freeways that have exit numbers are coordinated with mile markers.
