互联网名称与数字地址分配机构（Internet Corporation for Assigned Names and Numbers），简称ICANN，是美国加利福尼亚的非营利社团，主要由互联网协会的成员组成，创建于1998年9月18日，目的是接管包括管理域名和IP地址的分配等与互联网相关的任务，这些任务曾由其它组织（特别是IANA）代表美国政府来执行。

The Internet Corporation for Assigned Names and Numbers (ICANN /ˈaɪkæn/ EYE-kan) is a nonprofit organization that is responsible for coordinating the maintenance and procedures of several databases related to the namespaces of the Internet - thereby ensuring the network's stable and secure operation. ICANN performs the actual technical maintenance work of the central Internet address pools and DNS Root registries pursuant to the Internet Assigned Numbers Authority (IANA) function contract.
