Horst Jankowski (January 30, 1936 – June 29, 1998) was a classically trained pianist, most famous for his internationally successful easy listening music.

Born in Berlin, Jankowski studied at the Berlin Music Conservatory and played jazz in Germany in the 1950s, serving as bandleader for singer Caterina Valente. Jankowski's fame as a composer of easy listening pop peaked in 1965 with his tune "Eine Schwarzwaldfahrt", released in English as "A Walk in the Black Forest". The tune became a pop hit, reaching #1 on the US easy listening chart,#12 on the US Billboard Hot 100,and #3 on the UK Singles Chart. It sold over one million copies, and was awarded a gold disc. The track was featured on the BBC's review of the 1960s music scene, Pop Go The Sixties, broadcast on BBC One and ZDF, on January 1, 1970. The Genius of Jankowski album, released in 1965, was also a million seller.

Jankowski went on to score a string of successful albums, but moved on in the 1970s to concentrate more on jazz, including covers of pop and rock hits. Between 1989 and 1994 Jankowski composed and performed easy listening music for Sonoton, Germany.

Jankowski died of lung cancer in 1998, at the age of 62.
