Villivakkam (Tamil: வில்லிவாக்கம்) is a neighbourhood located in Chennai, Tamil Nadu. It is a residential area known for famous temples. Situated between the industrial estates of Ambattur, Padi, ICF, Perambur Locoworks , this place is populated mostly by the working class people of Chennai (especially people working in manufacturing).

According to legend, two demons, 'Ilvalan' and 'Vatapi', who were born to Sage Dhurva and Aswamukhi, tortured the entire world and killed many innocent people. One of the demons used to take the shape of a fruit and the other used to offer it to some innocent passer-by and after he consumed it, the demon would come out by tearing his stomach. It was left to Sage Agasthya to kill these demons with his mystic powers. It was here that the slaying of the demons took place and as a result the place came to be known as Konnur in times of yore.

It got the name of Villivakkam much later which has its own bearing - that Sage Agasthya planted a "Vilvam" plant (which has got medicinal and spiritual healing power) and hence the name. The Shiva temple in Villivakkam has a very old Vilvam tree which the priests consider sacred and use its leaves for the daily puja.
