The Halle Open is an ATP 500 event played on outdoor grass surfaces. It takes place in the Halle, North Rhine-Westphalia region of Germany each season. The Halle Open has been part of the ATP Tour for three decades after the event took place in 1993.
Originally, the competition was sponsored by German fashion businessman Gerry Weber up until 2018. Noventi then took over as the main sponsor before the competition was rebranded as the Terra Wortmann Open in 2021. Each season, the Halle Open is held at the same time as the Queen's Club Championships in the United Kingdom. As a result, it is considered one of the main ATP warm-up events before Wimbledon.
Also, the Halle Open proves to be a popular competition each year. Since 1993, over three million spectators have attended the grass-court event. As an ATP 500 tournament, the Halle Open has one singles draw of 32 entrants. However, it also hosts a doubles event of 16 teams.
In the singles, one player has dominated the Halle Open in recent years - Roger Federer. The former Swiss player won a record ten titles at Halle. In addition, he won the doubles competition on one occasion when playing alongside his countryman Yves Allegro.
There has been less dominance in the doubles draw at Halle. Since 1993, two players have had three titles in the doubles draw. Between 2015 and 2019, South African Raven Klaasen won the event three times. However, Brazilian player Marcelo Melo has matched this record as he also won three times between 2017 and 2023.
