The National Assembly Building (北京国会旧址) is the first purpose-built meeting place of the National Assembly (國會, Guóhuì) of the Republic of China in Beijing.

It was designed by Curt Rothkegel (1876-1945), a German architect based in Qingdao.

Rothkegel had made earlier (and grander) designs for a Parliament Building commissioned by the late Qing Dynasty, whose construction was started in 1910 on the site of today's Beijing International Hotel on East Chang'an Avenue, but was left unfinished at the time of the Xinhai Revolution in 1911.

The National Assembly Building is now part of the compound of Xinhua News Agency in central Beijing.

The Xinhua History Exhibition Hall, an in-house museum, is located in nearby Republican-era brick buildings.
