Bo Alexander Ljungberg (21 November 1911 – 19 March 1984) was a Swedish athlete. He won two silver medals in the pole vault at the European Championships and competed in the 1936 Summer Olympics as both a pole vaulter and a triple jumper.[1]
Bo Ljungberg won gold in the pole vault at the 1933 International University Games in Turin, clearing 3.90 m.[2] At the following year's European Championships, also in Turin, he jumped 4.00 m and won silver behind Germany's Gustav Wegner;[3] he also competed in the triple jump, placing 8th with 14.01 m.
He also took part in both events at the 1936 Summer Olympics in Berlin; in the triple jump he managed 14.35 m and placed eighteenth, while in the pole vault he again cleared 4.00 m and shared sixth place with ten others.[1] At the 1938 European Championships he repeated his silver medal from four years before, clearing 4.00 m once more.[2] In 1939 he won a second International University Games medal, clearing 3.90 m for third place.[2]
Ljungberg set his personal pole vault best, 4.15 m, in 1935,[1] breaking Henry Lindblad's Swedish record of 4.13 m from the 1931 Finnkampen.[4] The new record lasted until 1946, when Lars Andrén cleared 4.16 m.[5] Ljungberg's personal best in the triple jump was 14.73 m from 1934.[1]
