.mp is the Internet country code top-level domain (ccTLD) for Northern Mariana Islands. There are a few sites related to the Northern Mariana Islands in this domain (such as governmental sites under .gov.mp and a few sites in .org.mp and .co.mp). The get.mp site allows users to register and manage .mp domains. The .mp name comes from ISO 3166^[1] which specifies MP as the two letter designation for the Northern Mariana Islands.

Domain name registry services for .mp domains are operated by Saipan DataCom, a local ISP.^[2][3] Domains with four or more characters may be purchased for $20. Premium domains under four characters range in price, with two-character domains running $5,000 for a three-year registration. There are some sites related to the Northern Mariana Islands under third-level domains .gov.mp and .co.mp.

The MP Domain does not have public whois services available. Saipan DataCom will provide whois data in cases of potential trademark infringement.^[4] Although ICANN documents specify whois.nic.mp^[3] as of July 2018 this host does not resolve.

Saipan DataCom formerly operated chi.mp, a content hub and identity management platform providing .mp domains and websites. Old free .mp registrations provided earlier by chi.mp were terminated without a notice and the chi.mp web site has been defunct since at least May 2013^{[citation needed]}. As of August 2021 get.mp is offering chi.mp for sale for $20,000.00.^[5] Mailchimp uses .mp as a domain hack (mailchi.mp) to redirect to its main website.
