Ramnadi is river in Pune District and a tributary of Mula. It originates in the Sahyadries near Kathpewadi north-west of Pune city. The river flows through the Pashan, Baner and Aundh areas of Pune city. It is defined as a brook by the Pune Municipal Corporation (PMC). Some local people say that the basin of Ramnadi was shrieked^{[clarification needed]} in Pashan and Baner areas during illegal constructions. However, these constructions are yet to be removed. Many rallies have been held to save the river. However, it has been turned into a sewage canal due to over dumping of garbage. Hence PMC has undertaken a project to beautify this river.

The Pashan Lake also lies on this river.

Pune, formerly Poona (pronounced [puɳeː] ( listen)), is the eighth largest metropolis in India, the second largest in the state of Maharashtra after Mumbai, and the largest city in the Western Ghats. Once the centre of power of the Maratha Empire, it is situated 560 metres above sea level on the Deccan plateau at the confluence of the Mula and Mutha rivers. Pune city is the administrative capital of Pune district.

Pune is known to have existed as a town since 937 AD. Pune was originally called Punawadi. In 1730, Pune became an important political center as the seat of the Peshwa, the prime minister of the Chhatrapati of Satara; it was during this era that Pune became the centre of Indian politics. After the town was annexed to British India in 1817, it served as a cantonment town and as the "monsoon capital" of the Bombay Presidency until the independence of India.

Today, Pune is known for its educational facilities and relative prosperity. Pune is the cultural capital of Maharashtra.
