Poonamallee High Road, officially known as Periyar EVR High Road (National Highway 4), is an arterial road in Chennai, India. Running from east to west, the 14-kilometre (8.7 mi) road starts at Muthuswamy Bridge near Madras Medical College at Park Town and ends near Maduravoyal Junction via Kilpauk, Aminjikarai, Anna Nagar Arch, Arumbakkam, Koyambedu. It further continues west towards Poonamallee and traverses Sriperumbudur, Walajapet, and Ranipet. It connects two of the vital transport installations of the city, viz. Chennai Central railway station and the CMBT. The road has more hospitals than any other roads in the city and is popularly known as the city's 'Med street'.

Poonamallee High Road is six metres (20 ft) wide in most stretches, except for the stretch between Koyambedu and Anna Nagar Arch, which has only four lanes. The width of the road varies from two to nine lanes or from 12 to 35 metres (39 to 115 ft). The road narrows at the stretches between Ripon Building and Government Fine Arts College, Pachaiyappa's College and Shenoy Nagar junction, and DG Vaishnav College and Koyambedu. The road has not been widened since the 1980s. The road is used by more than 185,000 vehicles every day. Heavy containers from and to the Chennai Port use this road at night, making it one of the heavily worn roads of the city and necessitating regular re-laying. As of 2008, about 11,000 passenger cars cross any given point of the road every hour. As of 2013, this has been projected to 19,000 passenger cars, more than five times the designed capacity of the road.
