Novak Djokovic and Andy Murray will "no longer be working together", the tennis stars have announced.
Djokovic thanked his former rival "for all the hard work, fun and support" over the six months Murray worked as the head of his coaching staff.
The Serbian player added that he "really enjoyed deepening our friendship together".
Former world number one Murray said: "Thanks to Novak for the unbelievable opportunity to work together and thanks to his team for all their hard work over the past six months. I wish Novak all the best for the rest of the season."
The split comes just two weeks before the French Open starts on 25 May, where 24-time Grand Slam champion Djokovic is looking to win his fourth Roland Garros title.
The pair started working together ahead of the Australian Open in January, where an injury ended Djokovic's run in his semi-final match against Alexander Zverev.
Murray said during the tournament that he had not planned on jumping straight into coaching following his retirement last year, but that Djokovic's offer was too good to turn down.
He added that he enjoyed the tactical aspects of being Djokovic's coach and did not find sitting on the sidelines instead of playing on the court uncomfortable, but admitted that the job was more demanding than he anticipated.
Djokovic sang Murray's praises and highlighted the impact he had had as his coach.
The tennis star, who won 24 out of his 36 matches against Murray, said at the Qatar Open in February that the two-time Wimbledon champion would coach him for an "indefinite" period, including "some clay-court tournaments" this season.

The British coach worked with Djokovic in Indian Wells and Miami, where the Serb reached the final but failed his bid for a 100th tour-level title as he was defeated by Jakub Mensik.
Djokovic's form dipped following the Miami defeat, with the 37-year-old losing his opening matches at Masters tournaments in Monte Carlo and Madrid in April.
He skipped the first tournament of the clay season, the ongoing Italian Open, without giving a reason, as he is set to start in his first clay match at the Geneva Open next week after accepting a wildcard.
Djokovic, who is currently ranked sixth in the world, and Murray's coaching partnership ended without any titles.
His only title since 2023 was at the Paris Olympics last year, where he won the gold medal after beating Spaniard Carlos Alcaraz in the final.
