Tennessee's Non-venomous Snakes

(sometimes called chicken snake)

(also called red ratsnake, cornsnake)

*These snakes are very common statewide and are a good place to start if you are trying to ID a snake.


In Tennessee, it is illegal to harm, kill, remove from the wild, or possess native snakes taken from the wild without the proper permits.

Please help the Tennessee Wildlife Resources Agency (TWRA) to protect our native snakes. Do not remove snakes from the wild or release snakes that have been captive into the wild.

Once-captive snakes often don't survive in the wild and can introduce harmful diseases and parasites into the wild.
