.ng is the Internet country code top-level domain (ccTLD) for Nigeria. It is overseen by the Nigeria Internet Registration Association (NIRA).
The top-level domain was first delegated in 1995 to Ibukun Odusote at the Yaba College of Technology. She was made a life patron of the Nigeria Internet Registration Association in 2013 for her work.
Operations were initially handled by an organization in Italy, the Instituto per le Applicazioni Telematiche (today known as the '), but were later transferred to Randy Bush. In 2004, .ng was re-delegated to a Nigerian organization, the National Information Technology Development Agency, and then in 2009, to the Nigeria Internet Registration Association.
In addition, NIRA themselves reserve the right to register 'premium' top level domains under .ng (for example, "google.ng").
As of March 2022, there are 75 registrars accredited by NIRA. Almost 70% of all .ng domains are registered under .com.ng. 7% are registered under .org.ng, which is chiefly used by local non-profit organisations. Although registration at the second level (directly under .ng) is available, only 17% of active .ng domains are registered there. Third-level domains (such as those under .com.ng) are several times cheaper than second-level names, which the registry considers more valuable for their potentially shorter length.
In 2025, Nigerian media reported a coordinated push by public institutions and stakeholders to increase adoption of the .ng domain.
