Periapalayam is a village located on the banks of the Arani river about 40 km North-West of Chennai. It is part of the Ellapuram block in Tiruvallur District. Due to the recent increase in MSMEs along the North Chennai Development corridor, it is quickly becoming the primary residential area for the wave of workers working in the nearby SIPCOT industrial area. Located along the primary connecting road between Chennai and Tirupathi means it is well connected to the cities via public road transport. The village is also home to the famous Periyapalayam Bhavani Amman temple.
