The domain name gov is a sponsored top-level domain (sTLD) in the Domain Name System of the Internet. The name is derived from government, indicating its restricted use by government entities in the United States. The gov domain is administered by the General Services Administration (GSA), an independent agency of the United States federal government.

The U.S. is the only country that has a government-specific top-level domain in addition to its country-code top-level domain. This is a result of the origins of the Internet as a U.S. federal government-sponsored research network (see ARPANET and National Science Foundation Network). Other countries typically delegate a second-level domain for this purpose, for example: is the second-level domain for the Government of Canada and all subdomains.

Some U.S. federal agencies use rather than gov. The Department of Defense and its subsidiary organizations use the mil sTLD. Some U.S. governmental entities use other domains, such as com domains by the United States Postal Service (which uses both and for the same website, although it only advertises the com address), and the United States Army's recruitment website (, this trend is repeated at the recruitment websites of the other branches of the U.S. military).

All governments in the U.S. were allowed to apply for delegations in gov before May 2012,<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> such as for the city of Atlanta, for the county of Loudoun, Virginia and for the U.S. state of Georgia. This was not always true; under an earlier policy, only federal agencies were allowed to use the domain, and agencies beneath cabinet level were required to use subdomains of their parent agency. There is a lack of consistency in addresses of state and local government sites, with some using gov, some us, some using both (the Commonwealth of Pennsylvania uses, and for the same web site) and still others in com, org or other TLDs.
