The four Major tennis tournaments or Grand Slam tennis tournaments—sometimes called "championships", sometimes abbreviated "Tennis Majors" or even "Majors" or "Slams"—are the world's most important annual tennis tournaments. They are now most important by world tour ranking points, prize-money, strength and size of field, and public attention, and they have been considered most important for decades. The Grand Slam tournament itinerary is the Australian Open in January, the French Open in May/June, Wimbledon in June/July, and the US Open in August/September. The Australian and US tournaments are played on hard courts, the French on clay, and Wimbledon on grass. Wimbledon is the oldest Major, founded in 1877, followed by the US in 1881, the French in 1891, and the Australian in 1905.

The term Grand Slam primarily refers to the achievement of winning all four major championships in a single calendar year within one of the five disciplines: men's and women's singles; men's, women's, and mixed doubles. In doubles one team may accomplish that playing together or one player may do it with different partners. The term "Grand Slam" without qualification refers to winning the four majors in a single calendar year.

Winning the four majors in consecutive tournaments but not in the same year is known as a Non-Calendar Year Grand Slam, while winning all four majors at any point during a career is known as a Career Grand Slam. Winning the Olympic gold medal as well as the four Majors in a one calendar year is known as a "Golden Grand Slam". It has only been possible to achieve this during Olympic years since 1988, when tennis became an olympic event. Steffi Graf achieved a golden grand slam in 1988, and is the only player so far to do so. The four Majors in all three disciplines where one is eligible—singles, doubles, and mixed doubles—are called a "boxed set" of Grand Slam titles. No one has won all twelve in one calendar year but it has been done in a lifetime.
