Alligators (Alligator mississippiensis) are in Merchants Millpond State Park, North Carolina, just south of Dismal Swamp and at Kitty Hawk. None live naturally in Virginia - yet.
There is one adult alligator buried in the Pittsylvania County landfill. In 2006, a trucker ran over the unfortunate reptile in Florida and brought the carcass to Virginia. Wildlife officials confiscated it because alligators were a protected species. The alligator species is not listed as a "threatened or endangered" species by the US Fish and Wildlife Service now, but they resemble endangered crocodiles.
The trucker's plans to make a pair of boots were blocked. The dead alligator was seized and ultimately buried in the Virginia landfill.1
The North Carolina Wildlife Resources Commission authorized a hunting season in 2018, since the population had increased sufficiently within that state. The first legal hunt that year led to the harvest of one 20-year old alligator.2
A warming climate may result in a natural range expansion northward across the border into Dismal Swamp. The adults in Merchants Millpond State Park are living at the edge of their range. Some may decide one day to cross the state border, but a more likely migration route is up the Pasquotank River. Whenever alligators arrive, they are unlikely to breed within Virginia because of the cold temperatures.
However, if the climate warms significantly, alligators could adapt. Crocodillians such as alligators are remarkably capable of withstanding climate change, perhaps because they incubate their eggs at the same temperature wherever they nest. In contrast, turtles incubate at different temperatures at different latitudes. As the climate warms or cools, crocodillians still reproduce successfully while other species suffer.
Crocodillians survived the changing conditions that led to extinction of the dinosaurs, and have lasted nearly 100 million years on earth. Before the asteroid impact 65 million years ago that wiped out the dinosaurs (except birds), a type of crocodillian lived in the swamps which ultimately became the Midlothian coal fields south of Richmond.3

A state permit is required to keep a pet alligator or cayman in Virginia. The permit form notes:5
In 2012, Virginia Department of Game & Inland Fisheries seized an alligator in Virginia Beach. They took it to the Virginia Living Museum in Newport News, which named him Stallone because its smile resembled that of actor Sylvester Stallone. The alligator lived in the cypress swamp exhibit for six years. In 2018, it was sent to Alligator Adventure in North Myrtle Beach. That site serves as a "retirement home" for captured alligators.6
The Wildlife Center near Staunton has reported admitting a seized alligator as a "patient." It was transferred to the Luray Zoo and Reptile Center. The small privately-owned rescue zoo is not accredited by the Association of Zoos and Aquariums, but has the required permits by state and Federal officials to keep exotic animals. It accepts wildlife that can not be released into the wild, simplifying the lives of local officials who have seized alligators but have no place to keep them.7
Alligator sightings occur every few years, in all regions of Virginia. The Virginia Department of Game and Inland Fisheries has concluded that all such sightings are from escaped or released pets. For example, in 2005 a four-foot-long alligator was killed in the City of Chesapeake. That same year, a fisherman in Falling Creek Reservoir in Chesterfield County used an oar to club to death a three-foot long alligator which he hooked.8
In 2018, the Virginia Department of Game and Inland Fisheries reacted to a report that a 2-foot long alligator had been seen in Great Dismal Swamp National Wildlife Refuge. The state agency responded in a post on Facebook that it was probably a pet which someone had released. Later in 2018, a pet four-foot long alligator got loose in Big Moccasin Creek near Gate City. State officials killed it, for public safety.9
Alligators who escape can survive in the wild. In 2007 Stafford County police responded to a report that there an alligator was an alligator underneath a car, in a subdivision. The local animal control officer trapped it. The condition of the skin indicated that the alligator had spent a year in the wild. It may have been a farm-raised alligator or a pet, but it had been on the loose in Aquia Creek. 25 years earlier, another escaped/released alligator had been shot in Accokeek Creek.10
To survive freezing water at the northern end of their range, North Carolina's alligators stick their noses out of the water before the ice completely seals the surface. In 2019, 18 alligators at Shallotte River Swamp Park & Outdoor Adventure Center entered what the local manager called "a state of brumation, like hibernating."11
The official portrait of Gov. Terry McAuliffe includes a small alligator. The picture emphasizes him signing paperwork to restore voting rights to felons who have completed their sentences. The alligator is a humorous reference to a fund-raising stunt when McAuliffe was a Democratic Party official raising money for President Bill Clinton.12

at some point, swimmers in Virginia will need to watch out for alligators
