  Sinner then won his seventh title at the Open Sud de France in Montpellier, becoming the first player to win a tour-level title in the season without having dropped a single set and the first since countryman Lorenzo Musetti won the title in Naples in October 2022. At the ABN AMRO Open he defeated top seed and world No. 3 Stefanos Tsitsipas taking his revenge for the Australian Open loss, for his biggest win ever. Next in the quarterfinals, he defeated Stan Wawrinka in straight sets. In the semifinals, he defeated home favorite Tallon Griekspoor to reach the final, which he lost to sixth seed Daniil Medvedev.
  
  In March, he played in Indian Wells where he defeated Richard Gasquet, Adrian Mannarino, and Stan Wawrinka all in straight sets to advance to the quarterfinals where he faced defending champion Taylor Fritz and won in a three-set match. In the following round in the semifinals, he lost in straight sets to career rival and top seed Carlos Alcaraz who returned to world No. 1 following the tournament. In Miami, he reached the quarterfinals of this tournament for a third straight year after defeating Grigor Dimitrov and Andrey Rublev, thus returning to the top 10 in the rankings at world No. 9. He then defeated Emil Ruusuvuori to reach back-to-back semifinals, where he again faced the defending champion Carlos Alcaraz, this time winning to reach his second Miami and career Masters final in three years, putting an end to Alcaraz's hopes for a Sunshine Double and preventing him from returning to the No. 1 spot. He lost to fourth seed Daniil Medvedev in straight sets in the final, extending his losing streak versus the Russian to 0–6.
  
  In Monte Carlo he reached a third consecutive Masters semifinal defeating compatriot and 16th seed Lorenzo Musetti. At the French Open, Sinner was upset in the second round by Daniel Altmaier in a five-set match despite serving for the match in the fourth set and having two match points. At five hours and 26 minutes, it was the longest match of Sinner's career up until this point and the fifth-longest in the tournament history as well as the second longest of the season after Andy Murray against Thanasi Kokkinakis at the Australian Open.
  
  He reached back to back quarterfinals in Wimbledon after defeating Juan Manuel Cerundolo, Diego Schwartzman, Quentin Halys and Daniel Elahi Galán. He then reached his first Major semifinal after defeating Roman Safiullin, before losing to Novak Djokovic in straight sets. In August, he won his maiden Masters 1000 title at the Canadian Open, defeating compatriot Matteo Berrettini, Andy Murray by walkover, Gaël Monfils, and Tommy Paul en route to the final, where he beat Alex de Minaur in straight sets for his eighth ATP title.
  
  At the China Open, he defeated world No. 2 Carlos Alcaraz, his fourth tour-level win against the Spaniard, to reach his fifth final of the season, where he defeated world No. 3 Daniil Medvedev for the first time at the seventh time of asking. As a result, he climbed to a career-high world No. 4 to become the second Italian in the history of the ATP rankings to reach the Top 5, equaling Adriano Panatta. At the Shanghai Masters he lost in the round of 16 to Ben Shelton. He recorded his 55th win over Andrey Rublev to reach his fourth ATP 500 career final in Vienna and became the first Italian man with the most wins for a season in the Open Era, surpassing Corrado Barazzutti 's 54 mark in 1978. He won the final defeating again top seed Daniil Medvedev to win his tenth ATP title, defeating him in two consecutive finals.
  
  On his debut at the ATP Finals, Sinner won all of his round-robin matches, including beating the world No. 1 Novak Djokovic in a third set tiebreaker to clinch his fifth top-5 win in a row. He ultimately lost in a rematch against Djokovic in the final. He then made his debut in the Davis Cup, where he defeated Tallon Griekspoor in singles to help Italy win its quarterfinal tie against the Netherlands. In the semifinal, Sinner faced Djokovic for the third time in 11 days, and become the first player to defeat him in a Davis Cup singles match since Juan Martín del Potro in 2011. Sinner saved three consecutive match points in the third set to become only the fourth player to beat Djokovic from match points down and the first one to do so with three in a row. He also became only the third player ever to defeat Djokovic twice in 12 days, alongside Rafael Nadal and Andy Murray. Sinner then teamed up with Lorenzo Sonego for the decisive doubles match, defeating Djokovic and Miomir Kecmanovic to clinch the tie and help Italy reach the Davis Cup final for the first time since 1998. In the final, he defeated Australian Alex de Minaur to clinch the title for Italy for the second time after 47 years since 1976. Sinner was awarded the Most Improved Player of the Year award and voted the Fans' Favorite at the 2023 ATP Awards, while his coaches, Darren Cahill and Simone Vagnozzi, won the Coach of the Year award.
