The R548 is a Regional Route in South Africa. 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.

The R548 then re-enters Mpumalanga, and terminates at an intersection with the R51 just before Balfour.

The R548 is 52 kilometers (32 miles) long.
