The Sun Yat-sen or Zhongshan Memorial Hall is an octagon-shaped building in Guangzhou, capital of China's Guangdong Province.

The hall was designed by Lu Yanzhi and was built with funds raised by local and overseas Chinese people in memory of Sun Yat-sen. Construction work commenced in 1929 and completed in 1931.

The memorial hall stands on the site of Guangzhou's Presidential Palace during the Constitutional Protection Movement, when the Nationalists operated a rival "Chinese" government to the Zhili Clique's Beijing regime.

[citation needed] The palace was damaged during Ye Ju's 16 June 1922 attack on Sun Yat-sen, during which—though he had already fled—his wife narrowly escaped shelling and rifle fire before meeting him[1] on the gunboat Yongfeng,[2] where they were joined by Chiang Kai-shek.

A statue of Sun Yat-sen was erected in front of the main entrance.
