The 32-year-old still had six months remaining at the Johan Cruyff Arena.
Blind has made 19 appearances across all competitions this season and played all five matches as Netherlands reached the Qatar 2022 FIFA World Cup quarterfinal stage, losing to Argentina.
Blind was in his second spell at Ajax following a four-year spell in England with Manchester United.
He has won seven Eredivisie titles across those two stints with Ajax.
An official statement from Ajax read: "Ajax and Daley Blind have terminated their contract.
"The defender's contract was set to expire on June 30, 2023 but will now end on December 31, 2022."
Chief executive Edwin van der Sar said: "Over the course of the last few days, we reached an agreement with Daley to terminate his contract.
"I hope he can find another club to end his successful career with.
"Together with Daley, we have decided on a match in the Arena where he can say a proper goodbye to the supporters."
