The Eastern Diamondback resides in the palmetto flatwoods and dry pinelands of the South. It generally avoids marshes and swamps, but on occasion will live near the borders of wetlands. Occasionally it may venture into salt water, swimming to the outlying Keys off the Florida coast.


The Eastern Diamondback lives in the coastal lowlands, ranging from southeast North Carolina to eastern Louisiana, and throughout Florida, including the Florida Keys
