Andy Carroll, Adrian and Samir Nasri are to leave West Ham this summer, the club have announced.
The trio, along with Spanish striker Toni Martinez, will depart when their contracts expire at the end of June.
West Ham joint-chairmen David Sullivan and David Gold said in a statement on the club's website: "Andy and Adrian have both been great servants to West Ham United throughout their time at the club and we thank them for their loyalty and commitment to the claret-and-blue cause.
"Both have provided us and our fellow supporters with some unforgettable moments, whether they were sensational scissor kicks and unstoppable headers in Andy's case, or penalty saves and goals in Adrian's.
"They can both be assured of warm welcomes whenever they return to London Stadium and we wish them, as well as Samir Nasri and the young players whose contracts are up this summer, the very best for their future careers."
