The National University of Singapore (NUS) is a national public collegiate and research university in Singapore. It was officially established in 1980 by the merger of the University of Singapore and Nanyang University.

A public university or public college is a university or college that is owned by the state or receives significant funding from a government. Whether a national university is considered public varies from one country to another, largely depending on the specific education landscape. In contrast a private university is usually owned and operated by a private corporation. Both types are often regulated, but to varying degrees, by the government.
