.eu is the country code top-level domain (ccTLD) for the European Union (EU).

Launched on 7 December 2005, the domain is available for organisations in and residents of EU member states. The TLD is administered by EURid, a consortium originally consisting of the national ccTLD registry operators of Belgium, Sweden, and Italy, joined later by the national registry operator of the Czech Republic. Trademark owners were able to submit registrations through a sunrise period, in an effort to prevent cybersquatting. Full registration started on 7 April 2006.
