The Warlord Rebellion in northeastern Shandong was an uprising of several allied Chinese warlord armies under the leadership of Zhang Zongchang in 1929. The rebels wanted to regain their former territories in Shandong from Liu Zhennian, the man who had defected from Zhang to the Nationalist government in Nanjing during the Northern Expedition. After some initial successes, the rebels were defeated due to the indiscipline of their forces. In the end, the uprising failed to topple Liu Zhennian's rule over eastern Shandong, but resulted in high civilian casualties and widespread destruction at the hands of both sides in the conflict.

Zhang Zongchang, courtesy name Xiaokun, was a Chinese warlord who ruled Shandong from 1925 to 1928. A member of the Fengtian clique, Zhang was notorious for his brutal and ruthless behavior, eccentric personality, and extravagant lifestyle, which earned him nicknames such as the "Dogmeat General"; Time dubbed him China's "basest warlord". Zhang's troops were defeated by the National Revolutionary Army during the Northern Expedition in 1928, and he fled to Japan before returning to Shandong in 1932, where he was assassinated by a young officer.
