Cindrel Mountains (also known as Cândrel Mountains, Cibin Mountains, or the Szeben Alps) are a group of mountains in central Romania in the centre of the Southern Carpathians, in the North-East of the Parâng Mountains group.
From the Transylvanian Plateau, with heights between 200 and 400 m, in the North and East, the heights grow abruptly through a zone of deep valleys at about 900 m on the verge of the massif where some villages are situated. The heights continue to grow slowly towards the highest peak, Cindrel Peak, at 2,244 m. Only two other peaks in the range rise above 2000 metres: Balandrul Mare (2210 metres) and Starpului (2146 metres). 
Because the massif is easily accessible, the ethnographical area Mărginimea Sibiului has formed around the mountain, having sheep-herding and wood industry as the main occupations. On the Cibin river and on the Sadu river dams and hydro-electrical power plants were constructed, the oldest being the one from Sadu in 1896. The Păltiniș resort is situated halfway between the village of Rășinari and the Cindrel peak, with hotels, chalets and a ski slope. The resort has developed around a small monastery in which the Romanian philosopher Constantin Noica spent the last part of his life.
The main river flowing from the mountain is the Cibin river, which collects most of the other smaller rivers. Between the Cindrel Mountains and the Transylvanian Plateau, the river forms a wide depression the Sibiu Depression in which the main city in the area lies (Sibiu).
