While there have been occasional sightings of wolves in Texas, these are likely escaped or released captive wolves.
The Eastern Wolf (Canis lupus lycaon) is a subspecies of wolf that was once found in the Eastern United States, including Texas, but was driven to extinction in the state by the early 1900s.
Red Wolves, another subspecies, are found in the southeastern US, but their range does not extend into Texas.
The closest wild wolves to Texas are found in the Rocky Mountains and northern Canada.
