.as is the Internet country code top-level domain (ccTLD) for American Samoa. It is administered by AS Domain Registry.

There is no restriction on the nationality of registrants, and many .as names are registered to and used by people, companies and organizations with no connection to American Samoa (as example, people and organizations related to Asturias, a Spanish region). "AS" or "A/S" is a suffix indicating a joint stock company in some countries including Norway, Denmark and Czech Republic, so this TLD may be of use by companies of this sort. Also, some autonomous systems or websites providing information about autonomous systems or BGP, such as bgp4.as, have registered domain names.
