Karl Åke Seyffarth (15 January 1919 – 1 January 1998) was a Swedish speed skater who specialised in long distance events. He set new world records on the 5,000 m (8:13.7) in 1941 and on the 3000 m (4:45.7) in 1942. He became European Allround Champions in 1947, winning both the 5,000 m and the 10000 m on his way to becoming European Champion. In addition to speed skating, Seyffarth also was one of Sweden's leading cyclists, but this career was hampered by an injury in a dirt biking accident in 1943.
