Greece have appeared nine times at the FIBA World Cup, with their best result coming in 2006 as runners-up, after beating the United States 101–95 in the tournament's semi-final. Greece have taken part in the EuroBasket 28 times, winning the tournament twice, while also coming away with one silver (1989), as well as two bronze medals (1949, 2009). Some of the team's highlights at the competition were beating the Soviet Union 103–101 in the final in Athens to win their first title in 1987, and defeating Germany 78–62 in the final in 2005.
