Kudavasal or Kodavasal is a panchayat in Thiruvarur district in the Indian state of Tamil Nadu.

Located at the heart of the Cauvery delta, Kudavasal was a prominent settlement during medieval times.

Brahmin scholars migrating from the north of India to the Chola kingdom lived here.

Post-independence migration trends have seen native populations move to urban centers like Chennai, with subsequent settlement by the Muslim population resulting in a dramatic demographic shift.
