The 20th Group Army is a military formation of the People's Liberation Army Ground Force, stationed in the Jinan Military Region. It consists of two manoeuvre brigades with other attached or otherwise organic units. For some time after its formation in 1949, the army consisted of three divisions.

The 20th Army started as the communist Red Army Eastern Fujian Independent Division, a collection of guerrilla forces operating in Eastern Fujian Province during the 1920s. After the Japanese invasion, it was incorporated into the New Fourth Army as Third Support Group, 6th Regiment. It was first under the command of Jiangnan Headquarters, and then Subei Headquarters with a nickname, "Jiangnan Anti-Japanese Righteous and Brave Army" ( Jiangnan Kangri Yiyong Jun ).

In October 1940, it defeated the Nationalist's anti-communist elements in the battle of Yellow Bridge (Huang Qiao). After the Wannan incident of January 1941, the 6th Regiment was reformed as 1st Division, New Fourth Army. In December 1944, under the command of Su Yu, the 1st Division and its three main regiments, moved down south and crossed the Yangtze river and became the 4th Column of the Zhejiang Military District (MD), while the wounded remained in Jiangnan and formed the "Jiang Anti-Japanese Eastern Route Headquarters" and later became part of the 6th Division, 18th Brigade, New Fourth Army, eventually rejoining the 20th Army as 59th Division's 175th Regiment.

After the victory of the Anti-Japanese war in late 1945, and according to the treaty of Zhongqing, Zhejing MD's military forces were ordered to moved north into Shandong province and joined the newly formed Shandong Field Army as its 1st Column with Ye Fei and its commander and Lai Chuanzhu as the political commissar. The 1st Column's three main elements were the 1st Brigade (ex-Zhejiang 4th Column), 2nd Brigade (ex-Suzhong's MD's training brigade), and the 3rd Brigade (ex-Zhejing's 2nd Column).

In 1947, the Shandong Field Army was renamed as Huadong Field Army, and three brigades of the 1st Column were enlarged to Division size as the 1st, 2nd and 3rd Divisions. The 1st Column became the main fighting formation of the Huadong Field Army and took parts in epic battles such as Mengling, Yu Wan Su, and Huaihai.

In February 1949, the 1st Column was renamed and reassigned as PLA 20th Army of 3rd Field Army, 9th Army Group, with Lu Fei as its commander and Chen Shifu as the political commissar. Its three divisions were renamed as 58th, 59th, 60th Infantry Divisions. Right after the reform, the 20th Army took part in the battle of Yangtze Crossing, and Battle of Shanghai.
