The R548 is a Regional Route in South Africa that connects Delmas with Balfour via Devon.
Its northern terminus is the R50 east of Delmas, Mpumalanga. From there it first runs south, then south-east, crossing into Gauteng to reach Devon.
In Devon, it is briefly cosigned with the R29 when it intersects with it before leaving to the south-west. It gives off the west-south-westerly R550 and crosses the N17. It re-enters Mpumalanga and crosses the Suikerbosrand River to end its route at an intersection with the R51 just north of Balfour.
