UDRP stands for Uniform Domain Name Dispute Resolution Policy. It is a policy established by the Internet Corporation for Assigned Names and Numbers (ICANN) that provides a mechanism for resolving disputes over domain names that infringe on established trademarks.

Under the UDRP, trademark owners can file a complaint to challenge the registration of a domain name that is identical or confusingly similar to their trademark, and which is being used in bad faith. The complaint is typically filed with an approved dispute resolution provider, such as the World Intellectual Property Organization (WIPO) or the National Arbitration Forum (NAF).
