Kilvenmani massacre: Forty-four Dalits (untouchables) are burnt to death in Kizhavenmani village, Tamil Nadu, a retaliation for a campaign for higher wages by Dalit laborers.

The Kilvenmani massacre was an incident in Kizhavenmani village, Nagapattinam district of Tamil Nadu state in India on 25 December 1968 in which a group of around 44 people, the families of striking Dalit village labourers, were murdered by a gang, allegedly led by their landlords. The chief accused was Gopalakrishnan Naidu.

Dalit is a term used for untouchables and outcasts, who represented the lowest stratum of the castes in the Indian subcontinent. They are also called Harijans. Dalits were excluded from the fourfold varna of the caste hierarchy and were seen as forming a fifth varna, also known by the name of Panchama.

Kizhavenmani is a village in Nagapattinam district of Tamil Nadu state in India. The village is about 25 km from the district headquarters town of Nagapattinam. It is in the fertile river Cauvery Delta, known for its agrarian economy.
