Rudnik is a mountain in central Serbia, near the town of Gornji Milanovac. Its highest peak Cvijićev vrh, named after geologist and biologist Jovan Cvijić, has an elevation of 1,132 meters above sea level. It has several other peaks over 1000 m: Srednji Šturac, Mali Šturac, Molitve, Paljevine and Marijanac. Rudnik literally means 'mine' in Serbian, apparently referring to the mountain's rich mineral resources. The name is probably a testament to the mining activity associated with the mountain throughout several millennia.
