Barrackpore Trunk Road, commonly known as BT Road, is 4-6 laned trunk road in Kolkata metropolitan area, West Bengal, India. It connects Kolkata with its suburb Naihati via Barrackpore. Built in 1775, it is the oldest metalled road and one of the busiest roads in the country. The 18.1 km (11.2 mi) long road is a part of both State Highway 1 and State Highway 2.
Barrackpore Trunk Road has multiple institutes and other landmarks along it, including the Indian Statistical Institute and Rabindra Bharati University. Once the areas around the road were industrial zones, but gradually, residential areas sprawled and replaced the industries. The city's 160-year-old water supply pipeline runs under the road. An elevated metro line was planned in 2010–2011 over the road from Baranagar to Barrackpore. BT Road has a major intersection at Dunlop.
