"Secret Land" is a 1988 pop song by German singer Sandra. It was written by Uwe Gronau, Hubert Kemmler, Michael Cretu, , Susanne Müller-Pi, and Michael Höing, and produced by Cretu. It is an adaptation of the 1987 Kemmler-produced song "Trenchcoat Man" recorded by the short-lived German band Fabrique, the members of which were Gronau and Höing. In 1999, a remix of the song was released on Sandra's compilation My Favourites. It was released as a single to promote the album, but only met with minor success in Germany. The track was remixed again for her 2006 compilation Reflections.
