The Buckingham Canal is a major freshwater navigation canal in South India.

It runs parallel to the Coromandel Coast for approximately 400 miles. The waterway stretches from Kakinada in Andhra Pradesh to Pichavaram near Chidambaram in Tamil Nadu. This canal is vital because it connects many natural backwaters to the Chennai port. It serves as an important inter-state waterway for transporting large quantities of goods. Today, experts study the canal for its ability to protect coastal communities from natural disasters.

The canal functions by linking a series of natural backwaters along the coast. It is fed by tidal waters from the sea through various rivers and creeks. In the center of Chennai, the Cooum River connects the canal system to the Bay of Bengal. This connection allows for the movement of water between the ocean and the inland channels. Because of this structure, the canal is divided into two distinct sections. The North Buckingham Canal lies north of the Cooum River. The South Buckingham Canal is the portion located south of the river.

The history of the canal began with the construction of a saltwater navigation segment. In 1806, a stretch was built from Madras to Ennore. This first section was known as Cochrane's Canal after its financier, Basil Cochrane. In 1837, the government of the Madras Presidency took control of the waterway. They extended the canal north toward Pulicat Lake and south toward Marakkanam. For a short time, it was also called Lord Clive's Canal. The canal finally received its current name in 1878. This was named in honor of the Duke of Buckingham and Chandos, who ordered a specific link to be built.

Construction of the canal has often been tied to major historical events. Between 1877 and 1878, a terrible Great Famine occurred in Chennai. During this time, more than six million people perished. To provide relief work during the famine, a stretch linking the Adyar and Cooum rivers was built. This work cost 4.5 lakh rupees. Later, during the Second Five Year Plan, the central government contributed 115 lakhs of rupees to develop the canal. This funding aimed to link the canal with the Madras harbour to supplement railway capacity.

Despite its importance, the canal has faced significant decline in recent decades. The rise of railways and road transport reduced its use for moving goods. Cyclones in 1965, 1966, and 1976 caused physical damage to the structure. In Chennai, the water has become badly polluted by sewage and industrial effluents. The North Chennai Thermal Power Station discharges fly ash and hot water into the canal. Currently, nearly 60 percent of the 55 million litres of untreated sewage entering the city's waterways is let into the canal daily. This pollution and silting can create habitats for mosquitoes that spread malaria.

The canal also serves a critical role as a buffer zone during natural disasters. A buffer zone is a space that helps reduce the impact of a force. Dr. B. Ramalingeswara Rao identified this during the 2004 Indian Ocean tsunami. During that event, the canal acted as a regulator for the tsunami waves. The canal filled with tsunami water, which then receded back to the sea within 10 to 15 minutes. This process helped save the lives of many fishermen in Andhra Pradesh and Chennai.

Modern efforts are now focused on the rehabilitation and restoration of the canal. The Indian government declared the canal part of National Waterway 4 in November 2008. This plan involves developing both the North and South Buckingham sections. In Chennai, the Chennai River Restoration Trust was formed in 2010 to help restore the waterways. Some projects have focused on widening the South Buckingham Canal from Okkiyam Madu to Muttukadu. These improvements aim to use the canal as a macro drainage system to prevent flooding. By cleaning and deepening the channel, officials hope to turn the canal back into a useful asset for the region.
