Sven Anders Gärderud (born 28 August 1946) is a Swedish former track and field athlete, winner of the 3000 m steeplechase event at the 1976 Summer Olympics in Montreal. Gärderud was born to an orienteering competitor, and was an accomplished orienteer himself, winning a team gold medal at the 1977 Swedish Championships. He initially trained in orienteering and changed sports by chance – he was banned from running in the woods in autumn 1961 due to a jaundice epidemic and wandered into an athletic hall. Gärderud experimented with several events before focusing on the 3000 m steeplechase.
