Chocolate Puma are a DJ and music production duo from Haarlem, North Holland, consisting of René ter Horst ("DJ Zki") and Gaston Steenkist ("Dobre"). Their stage names include "Zki & Dobre", "The Good Men", and "Riva".

Zki & Dobre have produced dance music under various group names since the early 1990s.
