Karl-Gustav Fredrik Olausson (born October 5, 1966) is a Swedish former ice hockey player from Nybro who is currently assistant coach for HV71 in Elitserien.

During his career in NHL he has played for Winnipeg Jets, Edmonton Oilers, Mighty Ducks of Anaheim, Pittsburgh Penguins, and Detroit Red Wings.

During Elitserien playoffs in 2006, Olausson suffered a knee injury (torn ligament) in the third quarterfinal game with HV71 against Mora IK.

Unfortunately, it was reported on February 27, 2007, that Olausson would have to retire due to serious illness (primary sclerosing cholangitis).

In December 2006, he reportedly underwent two surgeries and received a liver transplant in the summer of 2007.
