Adayalampattu is a locality in the Thiruvallur district of Tamil Nadu, India, situated within the Poonamallee Tehsil.

It is a suburban neighbourhood, part of the Chennai metropolitan area. It is known for its residential properties and is in proximity to other areas like Vanagaram and Porur.

Potential merger

Despite being in close proximity to Chennai, Adayalampattu suffers from a lack of basic infrastructure. Essential amenities like proper roads, effective drainage systems, and a reliable water supply are missing. The residents of Adayalampattu hope that merging their area with the Greater Chennai Corporation will bring the much-needed infrastructure improvements, making their facilities comparable to other parts of the city.
