The N8 is a national route in South Africa that connects Groblershoop (south-east of Upington) with Maseru in Lesotho via Kimberley and Bloemfontein.

It runs east for 285 km, through Griekwastad, crossing the Vaal River at Schmidtsdrift, to Kimberley (Capital of the Northern Cape).

It enters as Schmidtsdrift Road, then Long Street, and reaches a junction with the N12, just west of the N12's intersection with the R64 (an alternative route to Bloemfontein).

The N8 joins the N1 highway northwards for 3 km up to the next off-ramp, where it meets the eastern terminus of the R64 (an alternative route from Kimberley).

After the Bloemfontein town centre, the N8 heads eastwards to form an interchange with the M10 metropolitan route (George Lubbe Street) and proceeds to bypass the Bram Fischer International Airport and the Air Force Base Bloemspruit.
