On this page, you can find an overview of the nine snake species found in Maine. Maine is one of the few states in the United States where no venomous snakes can be found. A few decades ago, occasional sightings of the venomous timber rattlesnake have been recorded in Southern Maine. But since it hasn’t been found in Maine for several decades, it has been declared extirpated in Maine.
