The Kanchipuram silk sari is a type of silk sari made in the Kanchipuram region in Tamil Nadu, India. These saris are worn as bridal & special occasion saris by most women in Tamil Nadu, Karnataka & Andhra Pradesh. It has been recognized as a Geographical indication by the Government of India in 2005–2006.

As of 2008, an estimated 5,000 families were involved in sari production. There are 25 silk and cotton yarn industries and 60 dyeing units in the region.

The saris are woven from pure mulberry silk thread. The pure mulberry silk used in the making of Kanchipuram saris comes from South India and the zari comes from Gujarat. To weave a Kanchipuram sari three shuttles are used. While the weaver works on the right side, his aide works on the left side shuttle. The border colour and design are usually quite different from the body. If the pallu (the hanging end of the sari) has to be woven in a different shade, it is first separately woven and then delicately joined to the Sari. The part where the body meets the pallu is often denoted by a zigzag line. In a genuine Kanchipuram Silk Sari, body and border are woven separately and then interlocked together. The joint is woven so strongly that even if the saris tears, the border will not detach. That differentiates the kanchivaram silk saris from the others.
