The R48 is a provincial route in South Africa that connects De Aar with Petrusburg on the N8 via Petrusville and Koffiefontein.

It begins by going eastwards into De Aar's northern suburbs up to the Friedlander street junction, where the R48 turns to the north-east.

It enters Philipstown in an easterly direction and meets the northern terminus of the R389 road at a junction in the town centre, where it turns northwards.

[1] From the R369 split west of Vanderkloof, the R48 heads north-north-east for 33 kilometres, crossing the Orange River into the Free State, to the town of Luckhoff.

It makes a left and a right turn before continuing northwards for 10 kilometres, crossing the Riet River, to reach a junction with the southern terminus of the R705 road.
