The National Art Center (国立新美術館, Kokuritsu Shin-Bijutsukan) (NACT) is a museum in Roppongi, Minato, Tokyo, Japan.

A joint project of the Agency for Cultural Affairs and the National Museums Independent Administrative Institution, it stands on a site formerly occupied by a research facility of the University of Tokyo and is adjacent to the National Graduate Institute for Policy Studies.

Unlike Japan's other national art museums, NACT is an 'empty museum', without a collection, permanent display, and curators.

Like Kunsthalle in German-speaking regions, it accommodates temporary exhibitions sponsored and curated by other organizations.
