The Grand Slam in tennis is the achievement of winning all four major championships in one discipline in a calendar year. In doubles, a team may accomplish the Grand Slam playing together or a player may achieve it with different partners. Winning all four major championships consecutively but not within the same calendar year is referred to as a "non-calendar-year Grand Slam", while winning the four majors at any point during the course of a career is known as a "Career Grand Slam".

This article covers the period 1884 to present. Before the beginning of the Open era in April 1968, only amateurs were allowed to compete in established tennis tournaments, including the four Grand Slams. Wimbledon, the oldest of the majors, was founded in 1877, followed by the US Open in 1881, the French Open in 1891, and the Australian Open in 1905. Beginning in 1905 and continuing to the present day, all four majors have been played yearly, with the exception of the two World Wars, 1986 for the Australian Open, and 2020 for Wimbledon. The Australian Open is the first major of the year (January), followed by the French Open (May–June), Wimbledon (June–July), and US Open (August–September).
