The Lithuania men's national basketball team represents Lithuania in international basketball competitions. They are controlled by the Lithuanian Basketball Federation, the governing body for basketball in Lithuania. Despite Lithuania's small size, with a population of less than 3 million, the country's devotion to basketball has made them a traditional force of the sport in Europe.

Basketball is a team sport in which two teams, most commonly of five players each, opposing one another on a rectangular court, compete with the primary objective of shooting a basketball through the defender's hoop, while preventing the opposing team from shooting through their own hoop. A field goal is worth two points, unless made from behind the three-point line, when it is worth three. After a foul, timed play stops and the player fouled or designated to shoot a technical foul is given one, two or three one-point free throws. The team with the most points at the end of the game wins, but if regulation play expires with the score tied, an additional period of play (overtime) is mandated.
