The '''Stuttgart Open'''{{efn|name=eurocard open|Not to be confused with the [[Eurocard Open]]. The Stuttgart Open has always been played outdoors, while the Eurocard Open was a tournament that was played indoors in Stuttgart from 1988–2001, with the exception of 1995 when it was played in [[Essen]]. The Eurocard Open was also the eighth [[ATP Masters Series|Super 9]] event on the [[ATP Tour]] from 1995–2001.}} (sponsored since 2022 by [[Hugo Boss]] and called the '''BOSS Open''') is an [[ATP Tour 250]] series professional [[tennis]] [[tournament]] on the [[Association of Tennis Professionals|ATP Tour]]. From 1970 to 1989, the Stuttgart Open was a [[Grand Prix tennis circuit]] event. From 1990 to 1999, the Stuttgart Open was an [[ATP Championship Series]] tournament. The Championship Series name was changed to [[ATP International Series Gold]] in 2000, and the Stuttgart Open was a part of this series from 2000–2001 and 2003–2008. In 2002, the Stuttgart Open was briefly demoted for one year to [[ATP International Series]] status, which was renamed to the ATP Tour 250 in 2009, and it has retained the classification ever since.
