The Pingjin Campaign  was part of the three major campaigns launched by the People’s Liberation Army during the late stage of the Chinese Civil War against the Nationalist government of the Republic of China.

The term Pingjin refers to the cities Beiping (now Beijing) and Tianjin.

The campaign, lasting from November 29 until January 31, 1949, marked the end of Nationalist dominance in northern China.
