Karl "Gösta" Åsbrink (18 November 1881 – 19 April 1966) was a Swedish gymnast and modern pentathlete who won a gold medal in the 1908 Summer Olympics and a silver medal in the 1912 Summer Olympics. Åsbrink's 1908 gold medal was won in London for a team event, as the Swedish men's gymnastics team came in first. Four years later, competing before a home audience in 1912 Stockholm, he won an individual silver medal in the first contested Modern pentathlon of the Olympic Games. Åsbrink was a lieutenant of the Swedish Army at the time and was later promoted to major.
