The Tamil Nadu Forest Department (TNFD) plays a significant role in the conservation of turtles, particularly marine turtles, along the state's coastline. Tamil Nadu’s coastal habitats are crucial nesting and foraging grounds for several turtle species, especially the Olive Ridley Turtle (Lepidochelys olivacea), which is classified as Vulnerable under the IUCN Red List.

Turtle conservation by the Tamil Nadu Forest Department is a multifaceted initiative involving protection, community involvement, law enforcement, and scientific research. Through consistent efforts, Tamil Nadu continues to be one of the key regions in India supporting the survival and recovery of marine turtle populations.
