Chennai suburban is the complex railway system that services the city of Chennai and its suburbs.

The system can be broken down into four sections:
- Central - Avadi - Tiruvallur - Arakkonam
- Central - Ennore - Gummidipoondi
- Beach - Tambaram
- MRTS
The system uses broad gauge. The section from Washermanpet to Beach handles predominantly freight traffic from Chennai Port, and is not geared well to serve passengers.
The MRTS system, when it is extended, will meet the suburban line to Tambaram at St Thomas Mount.
