Raik Hannemann (born 19 February 1968) is a retired German swimmer who won three medals in medley events at the LEN European Aquatics Championships of 1985–1989.

The drugs included a specially developed nasal spray that administered anabolic steroids with effects undetectable three days after use.

After retirement around 1990 he became a sports reporter for a small Berlin newspaper Kurier am Abend.

The same year he wrote a series of articles and took part in televised interviews exposing the past doping practices.

He blamed the doping problem on the East German Sports Federation, but believed that it had spread worldwide.
