List of 2018–19 Super Rugby transfers (South Africa)

This article documents player transfers involving the South African Super Rugby teams for the 2019 Super Rugby season. Super Rugby is a professional men's rugby union competition involving teams from Australia, New Zealand, South Africa, Argentina, and Japan (until 2020). This list focuses specifically on the movement of players into, out of, and within the four South African franchises participating in the tournament: the Bulls, the Lions, the Sharks, and the Stormers.

The information typically includes the player's name, their previous team or union (if applicable), and their new team within Super Rugby. This list aims to provide a comprehensive overview of the personnel changes impacting each South African team ahead of and during the 2019 season. It serves as a reference point for tracking player movements and understanding the composition of each squad. Transfers may include players joining from other rugby leagues (such as the Currie Cup in South Africa, or leagues in Europe or Australia), players moving between Super Rugby franchises, and academy players being promoted to the senior squad. Details may also include loan agreements, temporary transfers, and retirements where relevant to the composition of the squads.
