Anna Karin Larsson (later Ahlström, 30 August 1941 – 21 September 2019) was a Swedish swimmer who won a bronze medal at the 1958 European Aquatics Championships in the 4×100 m freestyle relay.[1] She competed in the same event at the 1956 and 1960 Summer Olympics and finished sixth in both games. Individually, she was eliminated in the preliminaries of the 100 m and 400 m freestyle.[2][3]
Larsson retired from active swimming in 1962 to focus on her studies; she graduated in physiotherapy from Lund University. However, she later returned to the pool and competed for a few years in the masters category. She also worked as a swimming coach and as instructor with disabled persons. She had three children: Peter Ahlström (b. 1965), Mats Ahlström (b. 1967) and Katarina Ahlström (b. 1970).[1] Her mother died when Larsson was 19 years old. Her younger sister, Kristina, and brother, Gunnar are also former Olympic swimmers; Kristina competed with the same 4×100 m freestyle team at the 1960 Olympics.[2]
