The Old Naini Bridge is one of the longest and oldest bridges in India, located in Prayagraj.

It is a double-decked steel truss bridge which runs across the Yamuna river in the southern part of the city.

The bridge runs north-south across the Yamuna river connecting the city of Prayagraj to the neighbouring area of Naini.

Its upper deck has a two lane railway line which connects Naini Junction railway station to Allahabad Junction railway station, while the lower deck has successfully been facilitating roadway services since 1927.
