The N12 Southern Bypass is a section of the Johannesburg Ring Road located in the city of Johannesburg, South Africa. The freeway was the last section of the Ring Road to be built, opening in 1986. From the west, the Southern Bypass begins at the Diepkloof Interchange, where it splits from the N1 freeway. It ends at the Elands Interchange, where it merges with the N3 freeway. Other interchanges include Ridgeway, Xavier Street, Klipriver Drive, Comaro, Reading, and Voortrekker Road.

As with the N1 Western Bypass, the freeway was built with concrete and has always been three lanes wide in either direction, fanning out into four lanes at Reading. The freeway passes through a declared green belt area to the south of Johannesburg, which has prevented the construction of billboards along the roadside, a common practice in the city.
