Pending the approval of his work permit, the move will take effect ahead of the 2026-27 campaign.
Van der Merwe, who has earned three international caps with the world-champion Springboks, enjoyed a dream start to his Test career by scoring twice on debut against Georgia last July. He also played a role in Rugby Championship victories over both New Zealand and Australia.
A native of Mpumalanga, he came through the ranks with the Pumas at underage level before joining the Cheetahs, where he made his PRO14 debut in 2018.
Since linking up with the Scarlets in September 2024, Van der Merwe has gone on to make 38 appearances for the Welsh region.
"I'm excited and honoured to be joining such a prestigious club, with such a proud rugby history. I want to finish the season strong with the Scarlets, before tackling this new challenge with Munster."
Munster general manager Ian Costello was understandably delighted with the signing of a world-class international player.
"He has been one of the best hookers in the URC over the past two years resulting in a call up to the Springbok squad.
"He is a physical, abrasive hooker, very strong in the setpiece, excellent over the ball, and now has demonstrated his ability to perform at international level.
"Marnus is passionate, and extremely ambitious and has the qualities that will make him a really good fit to our playing group. We look forward to welcoming him to Munster this summer."
