Which Grand Slam tournament is nicknamed the Happy Slam?

The Grand Slam tournament nicknamed the “Happy Slam” is the Australian Open.

The Australian Open is the first of tennis’s four annual Grand Slam tournaments. It is played in Melbourne during the Australian summer, usually in January, and its relaxed atmosphere, enthusiastic crowds and modern facilities helped make the nickname popular. Roger Federer has often been credited with coining or popularising the phrase among players.

The tournament began in 1905 as the Australasian Championships and was renamed the Australian Championships in 1927 before adopting the name Australian Open in 1969. It moved among several Australian and New Zealand venues before settling at Melbourne Park in 1988.

A common mix-up is confusing the nickname with an official title: “Happy Slam” is an affectionate, unofficial label, not the tournament’s formal name. The Australian Open is also played on hard courts, unlike the French Open’s clay, Wimbledon’s grass and the US Open’s hard courts.
