Delhi Ridge, sometimes simply called The Ridge, is a ridge in the Northern Aravalli leopard wildlife corridor in the National Capital Territory of Delhi in India. It is a northern extension of the ancient Aravalli Range, some 1.5 billion years old. The ridge consists of quartzite rocks and extends from the southeast at Tughlaqabad, near the Bhatti mines, branching out in places and tapering off in the north near Wazirabad on the west bank of the river Yamuna, covering about 35 kilometres.

The Aravalli Range is a mountain range in Northern-Western India, running approximately 670 km (420 mi) in a south-west direction, starting near Delhi, passing through southern Haryana, Rajasthan, and ending in Ahmedabad Gujarat. The highest peak is Guru Shikhar on Mount Abu at 1,722 m (5,650 ft). The Aravalli Range is arguably the oldest geological feature on Earth, having its origin in the Proterozoic era.
