166 Rhodope is a main belt asteroid, a member of the Adeona family of asteroids. It was discovered by the German-American astronomer Christian Heinrich Friedrich Peters on August 15, 1876, in Clinton, New York, and named after Rhodope, the queen in Greek mythology who was turned into a mountain.

166 Rhodope was observed occulting the prominent star Regulus on October 19, 2005, from Vibo Valentia, Italy.^[3]
