Bo Evert Ericson (28 January 1919 – 14 February 1970) was a Swedish hammer thrower who won a gold medal at the 1946 European Athletics Championships in Oslo with a throw of 56.44 metres. He was also a finalist at the 1948 Olympics in London, but he finished in sixth place with a throw of 52.98 metres. Ericson twice broke the Swedish national record for the hammer throw–in 1941 with a throw of 56.66 metres and, secondly, in 1947 with a throw of 57.19 metres–and held the record outright from 1941 until 1955. He was a ten-time winner of the hammer throw at the Swedish national championships.
