Sture Helge Vilhelm Pettersson (30 September 1942 – 26 June 1983) was a Swedish cyclist.

[1] Petterson turned professional after the 1969 World Championships, together with the other brothers, but had little success and retired in 1972.

At a 1964 race in Malmö he fainted 12 km before the finish; his brother Gösta rode nearby and managed to catch him from falling.

Sture died aged 40, probably due to a ruptured blood vessel in the brain.

[2] His grandson Marcus Fåglum also became a leading road racing cyclist.
