Tony Holiday (born Rolf Peter Knigge 24 February 1951 – 14 February 1990) was a German pop singer and songwriter.

Knigge was born in Hamburg, Germany. He began his career initially as a textile businessman and fashion designer. In 1974, he received a record contract with Hans Bertram, who rechristened him "Tony Holiday". His first two singles met with little success. Holiday's breakthrough came in 1977 with the German recording of "Tanze Samba mit Mir" ("Dance the Samba With Me") in 1977. The song quickly became a hit in both Germany and Austria, peaking at No.4 on the German music charts and reaching the Top 20 on the Austrian music charts. In 1979, he participated with the title "Zuviel Tequila, zuviel schöne Mädchen" ("Too Much Tequila, Too Many Beautiful Girls") in the German finals for the Eurovision Song Contest and the song finished in ninth place.
