  Entering the 2025 Australian Open as the defending champion, Sinner beat Nicolás Jarry, Tristan Schoolkate, Marcos Giron, Holger Rune, and Alex de Minaur on his way to the semifinals. In the semifinals, he defeated Ben Shelton in straight sets. He then defeated Alexander Zverev in straight sets to defend his title in the championship match on 26 January.
  
  For his 2024 positive test for Clostebol, the World Anti-Doping Agency (WADA) announced in February 2025 they entered a "case resolution agreement" with Sinner. WADA accepted the cause and explanation of the positive test but stated "an athlete bears responsibility for the entourage's negligence". A three-month suspension was handed down with Sinner being ineligible from tennis competition from 9 February to 4 May 2025. Some players reacted with criticism of the process, notably Novak Djokovic who at a press conference at the 2025 Qatar Open expressed the opinion that "the majority of the players feel like there is favouritism happening" citing the advantages that high ranked players have to rapid legal advice. Sinner's lawyer Jamie Singer was vocal of the criticism, speaking out about the ill-informed commentary about the process and the suspension itself.
  
  In May 2025, he reached the final of the Italian Open, defeating Mariano Navone, Jesper de Jong, Francisco Cerúndolo, Casper Ruud and Tommy Paul on his way to the final. In doing so, he became the first Italian man to reach the final of the Italian Open since Adriano Panatta in 1978. Sinner was defeated in the final by Carlos Alcaraz in straight sets. In the French Open he reached the finals beating Arthur Rinderknech in the first round, Richard Gasquet in the second round, Jiri Lehecka in the 3rd round, Andrey Rublev in the 4th round, Alexander Bublik in the quarter finals and Novak Djokovic in the semi finals. All matches up until the final were won without dropping a set. Sinner eventually lost the final, the longest in Roland Garros history, to Carlos Alcaraz, in spite of having been up two sets to love and having three match points in set four.
