What Religion is Jannik Sinner?
Sinner was raised in the Catholic faith, as is common in his native region. Multiple sources note that he grew up in a devout Roman Catholic family. He has not publicly emphasized his religious practices, but his background is clearly Catholic. For example, in May 2025 he made headlines by visiting Pope Leo XIV at the Vatican, presenting the new Pontiff with one of his tennis rackets. (They even joked about playing tennis together in the Holy See, with Sinner offering to volley a tennis ball as the Pope smiled.) Beyond such symbolic moments, little is known about Sinner’s church attendance or personal devotions. But he has spoken appreciatively of Italy’s Catholic heritage, and news reports continue to describe him as coming from a Catholic family.
Early Life
Jannik Sinner was born on 16 August 2001 in Innichen (San Candido) in northern Italy’s South Tyrol region. Growing up in the Dolomites, he split his youth between skiing and tennis. In fact, Sinner was a top junior skier – winning a national giant slalom championship at age seven and finishing runner-up at 11– before ultimately focusing on tennis at 13. His family background is South Tyrolean German-speaking; Sinner’s parents, Johann and Siglinde, worked at a mountain ski lodge. He also has an older adopted brother, Mark, who was born in Russia in 1998. These alpine roots and multilingual upbringing (German mother tongue) shaped his early years, before he moved to the Italian Riviera at 14 to train professionally.
Career Highlights
Sinner quickly climbed the tennis ranks. He became the first Italian man to reach world No. 1 in the ATP rankings (a status he first achieved in June 2024). In 2024 he won two Grand Slam titles – the Australian Open and the US Open – and the year-end ATP Finals. He also led Italy to back-to-back Davis Cup championships in 2023 and 2024.
The momentum continued in 2025: Sinner defended his Australian Open title and captured the Wimbledon crown (the first Italian man to win Wimbledon). In between those victories he reached the French Open final. By age 23 he had racked up multiple Masters 1000 titles and set several records (see Trivia). His powerful baseline game and mental strength have made him one of the dominant players on tour – and earned him a ranking as high as world No. 1 in singles.
Personal Life
Sinner maintains a fairly private personal life despite his fame. He is multilingual – fluent in German, Italian and English – and has lived in Monte Carlo, Monaco, since age 18. Off the court he enjoys skiing (his first sport) and has hinted that family time is important to him.
In recent years Sinner’s romantic relationships have drawn some media attention. From 2020–2024 he was linked with Italian model Maria Braccini, and in 2024 he went public with a relationship with Russian tennis player Anna Kalinskaya. The couple split by mid-2025. On Sunday, Oct. 26, the Italian tennis pro, Jannik Sinner reveals he’s dating model Laila Hasanovic during his victory speech at the Vienna Open.
