May Fourth Square is a large public square in Qingdao’s central business district. Named after the nationwide protest May Fourth Movement that started in Qingdao, the square is best recognized by the large "May Wind" sculpture near the seaside.

The May Fourth Movement was an anti-imperialist, cultural, and political movement which grew out of student participants in Beijing on May 4, 1919. They protested against the Chinese government's weak responses to the stipulations of the Treaty of Versailles, especially it allowing Japan to receive territories in Shandong, which had been surrendered by Germany after the Siege of Tsingtao in 1914. The May 4th Movement influenced the Chinese delegation not to sign the Treaty of Versailles.
