Stefan Bengt Edberg (born 19 January 1966 in Västervik, Sweden) is a former World No. 1 professional tennis player (in both singles and doubles) from Sweden. A major proponent of the serve-and-volley style of tennis, he won six Grand Slam singles titles and three Grand Slam men's doubles titles between 1985 and 1996. He also won one season-ending championship title, the Masters Grand Prix. In addition he won four Masters Series titles and four Championship Series titles.

Edberg first came to the tennis world's attention as a junior player. He won all four Grand Slam junior titles in 1983 to become the first-ever player to achieve the "Junior Grand Slam". Later that year as a professional, Edberg won his first career doubles title in Basel. Edberg accidentally caused the death of Dick Wertheim with an errant serve during the 1983 US Open.

In 1984, Edberg won his first top-level singles title in Milan. Edberg also won the tennis tournament at the 1984 Summer Olympics when the sport was an exhibition event and partnered with fellow Swede Anders Järryd to reach the final of the US Open. Edberg also reached the French Open doubles final with Järryd in 1986 and consequently was World No. 1 in doubles in that year.
