The Wales national rugby union team toured southern Africa in June 1998, playing test matches against Zimbabwe and South Africa, as well as tour matches against the Emerging Springboks and three of the South African provincial sides.
Wales head coach Kevin Bowring had resigned at the end of the 1998 Five Nations Championship, and with a replacement yet to be appointed, Dennis John was made caretaker coach ahead of the tour. Prior to the tour, 18 players from Wales made themselves unavailable to participate, while a further 8 picked up injuries during the tour.
Wales won their initial match against Zimbabwe in Harare, before moving on to the second leg of the tour in South Africa. Here they would play four tour matches against representative and provincial opposition and a test match against the Springboks. Wales lost all four of the tour matches, and then were defeated by South Africa in the test match. The final scoreline of 96–13 was the biggest defeat Wales had ever had, and remains so as of 2024.
