Gösta Artur Roland Pettersson (born 23 November 1940) is a retired Swedish cyclist. As an amateur, he competed in the individual and team road events at the 1960, 1964 and 1968 Olympics and won one silver and two bronze medals, in 1964 and 1968. In 1968 he also took part in two track events: individual and team 4000 m pursuit. Pettersson's brothers, Erik, Sture and Tomas, were also Olympic cyclists, and their quartet was known as the Fåglum brothers. They won the World Amateur Cycling Championships in 1967–1969 and a team silver medal at the 1968 Summer Olympics; three of the brothers were also part of the bronze-winning road team at the 1964 Games. In 1967 they were awarded the Svenska Dagbladet Gold Medal. After the 1969 World Championships the Fåglum brothers turned professional.
