Hans Lennart Olofsson Strandberg (26 March 1915 – 23 December 1989) was a Swedish sprinter. He specialized in the 100 metres event, in which he won a bronze medal at the 1938 European Championships and finished sixth at the 1936 Summer Olympics. In 1938, he also won a silver medal with the Swedish 4 × 100 m relay team.
Strandberg held Swedish titles in the 100 m (1934–38, 1940–43, 1945 and 1947), 200 m (1934–45), 4 × 100 m (1934–38, 1942–44, 1946–47 and 1950–52) and 4 × 400 m events (1935, 1937 and 1939). His 1936 Swedish record in the 100 m equaled the world record. His son Bobby was a national sprint coach in the 1960s.
