The three-year agreement with the Antalya-based group includes the addition of 10 luxury properties from 2024.
Andrew Flintham, managing director of Tui UK and Ireland, said: "I am delighted that we’re working with Rixos on an exclusive basis, so our customers can enjoy their luxurious resorts in popular destinations like Turkey and Croatia.
"The demand for quality, all-inclusive accommodation remains really strong, and this partnership will now provide Tui customers with outstanding choice."
The agreement extends Tui’s current exclusivities with Rixos Hotel Group from four to 10 hotel units and will include properties such as Rixos Dubrovnik and the Land of Legends Hotel.
Exclusivities across all 10 Rixos resorts will be made available to Tui’s 13 source markets for the summer 2024 season.
