In tennis, a Grand Slam is the achievement of winning all four major singles tournaments in the same calendar year, or more broadly achieving that feat across a career. The four major tournaments are the Australian Open, French Open, Wimbledon, and US Open. The Grand Slam is considered a benchmark in tennis.

Definition

A Grand Slam in tennis refers to winning the Australian Open, French Open, Wimbledon, and US Open. In common usage, it may mean either a calendar-year sweep or the broader career achievement of winning all four majors.

Calendar-year Grand Slam winners

The calendar-year Grand Slam in singles has been achieved by only a handful of players. ESPN and the US Open list Don Budge, Maureen Connolly, Rod Laver, Margaret Court, and Steffi Graf among the winners. Don Budge was the first to complete the feat in 1938.

Career Grand Slam

A career Grand Slam is completed when a player wins each of the four majors at least once. As of 2026, the men’s career Grand Slam list includes Carlos Alcaraz, Novak Djokovic, Rafael Nadal, Roger Federer, Andre Agassi, Roy Emerson, Rod Laver, Don Budge, and Fred Perry.

Novak Djokovic and Margaret Court are the all-time leaders in Grand Slam singles titles, each with 24. Serena Williams is the Open Era women’s singles leader with 23 titles.
