The National Olympic Committee of Lithuania () fielded a team of 67 athletes, 48 men and 19 women, across 15 sports at the Games. It was the nation's second-largest delegation sent to the Olympics, just four athletes short of the record achieved in Beijing 2008 (71). As usual, the men's basketball was the only team-based sport in which Lithuania qualified for the Games. Lithuania marked its Olympic debut in tennis and women's judo, as well as its return to weightlifting after missing out of the previous Games.
