Muttukadu boat house, Water sports complex in Muttukadu, Tamil Nadu, India

Muttukadu Boat House is a TTDC boating and water-sports facility on the East Coast Road in Thiruporur taluk, Chengalpattu district, Tamil Nadu. It sits on the Muttukadu backwaters, a shallow coastal waterbody linked to the Bay of Bengal, where the South Buckingham Canal enters and spreads into the estuarine system. The complex has a bamboo-roofed lounge, a floating jetty and a restaurant.

The facility was established in 1984 by the Tamil Nadu Tourism Development Corporation to provide public water recreation access. Infrastructure additions including a bamboo structure and floating jetty came later to enhance operations.

The boat house sits on the Muttukadu backwaters, a shallow estuarine system linked to the Bay of Bengal, where the South Buckingham Canal empties into the water before the seasonal sea opening. TTDC runs it as a stop on its Chennai–Mamallapuram circuit, and the one-day tours include it. The Seanz Cruise, a double-deck floating restaurant opened on 7 January 2025 under a public–private partnership with Grandeur Marine International, drew over 3,000 visitors in its first three months.

Access is by the East Coast Road, which links the site with Chennai to the north and Mamallapuram to the south; Metropolitan Transport Corporation buses serve the area, and there is no direct rail connection, so onward road transport is needed from Chennai's suburban and rapid-transit networks. Chennai International Airport is the nearest major airport. Boating depends on water levels and quality in the backwaters, which tidal exchange, rainfall and the seasonal sea opening affect; sewage inflow, shallow water and siltation have at times curtailed rides.

During the 2015 Chennai floods, boats from Muttukadu were used to rescue people in the city's outskirts. The facility's craft were thus put to emergency use rather than recreation.
