The Sino-Albanian split (Chinese: 中阿破裂; pinyin: Zhōng-Ā pòliè) in 1978 saw the parting of the People's Republic of China (PRC) and People's Socialist Republic of Albania, which was the only Eastern European nation to side with the PRC in the Sino-Soviet split of the early 1960s.

The relations between Communist Party of China (CPC) and the Party of Labour of Albania (PPSh) had stagnated by 1970. When China began to reemerge from isolation in the early 1970s, Mao Zedong and other Communist Chinese leaders reassessed their commitment to Albania. In response, Tirana, led by Enver Hoxha, began broadening its international position. Albania opened trade negotiations with France, Italy and the newly independent Asian and African states, and later in 1971 it normalized relations with Yugoslavia and Greece. Albania's leaders abhorred the PRC's rapprochement with the United States in the early 1970s. Tirana press and radio ignored President Richard Nixon's trip to Beijing in 1972. Nevertheless, Albania proposed the key resolution in the UN General Assembly which enabled the PRC to replace the Republic of China in the United Nations.
