Karl Gustaf Emanuel "Carl, Calle Aber" Abrahamsson (1 May 1896 in Södertälje, Sweden – 25 December 1948) was a Swedish track and field athletic, bandy and ice hockey player who competed in the 1928 Winter Olympics. He was also a coach and captain, mainly in the Swedish club Södertälje SK.
Abrahamsson participated in building the bandy section of Södertälje SK (SSK) during the 1920s. He was recruited to AIK's bandy team and played with the side in the Swedish championship finals against IFK Uppsala in 1915 and 1917. Abrahamsson also had a successful career in track and field, where he won 28 district championship in various sports and represented Sweden at the Baltiska spelen in Malmö 1914. During this time he gained a lot of attention in the Swedish press and was compared to Douglas Fairbanks in terms of spirit and athleticism.
Abrahamsson's younger brother, Erik Abrahamsson, started playing ice hockey in 1921 and played with AIK and IFK Stockholm, and also in the Swedish national ice hockey team. Erik and Carl managed to convince SSK's board of directors to incorporate ice hockey in the club. In the same year, SSK played in the Swedish championship final and won the title as Swedish champions after Abrahamsson scored the gaming winning goal against Västerås SK.
Abrahamsson was selected for the Swedish national team for the first time in 1926 and won the silver at the 1928 Winter Olympics in St. Moritz. He also played at the 1931 World Championships and the 1932 European Championships. He was later awarded with the Stora Grabbars Märke.
