The second encirclement campaign against the Shaanxi–Gansu Soviet was an encirclement campaign launched by the Chinese Nationalist Government that was intended to destroy the communist Shaanxi–Gansu Soviet and its Chinese Red Army in the local region. It was responded by the Communists' second counter-encirclement campaign at Shaanxi–Gansu Soviet (Chinese: 陕甘苏区第二次反围剿), also called by the communists as the second counter-encirclement campaign at Shaanxi–Gansu Revolutionary Base (Chinese: 陕甘革命根据地第二次反围剿), in which the local Chinese Red Army successfully defended their soviet republic in the border region of Shaanxi and Gansu provinces against the Nationalist attacks from April 1935 to July, 1935.
