Feng Zhanhai (simplified Chinese: 冯占海; traditional Chinese: 馮占海; pinyin: Féng Zhànhǎi; 6 November 1899 – 14 September 1963), or Feng Chan-hai, was one of the leaders of the volunteer armies resisting the Japanese and the puppet state of Manchukuo in northeast China.

At the time of the Mukden Incident and Japanese invasion of northeast China he was a colonel commanding a regiment of the Jilin Guards Division.

After the Mukden Incident, he opposed the Northeast border defense headquarters surrender to the Japanese forces, and commanded his troops on September 19 to withdraw from the Jilin provincial capital, and sent his troops during October to oppose the Japanese, fighting near Binxian.

He then called for volunteers, and the Public Safety Bureaus in the local districts turned over to them their police and militia, and established Feng as the General in command of a force, the Northeastern Loyal and Brave Army, of 15,000 men in the hills with the capital of Jilin City to his south and the metropolis of Harbin to his north.

There he was able to wreak havoc on the Japanese rail communications on the Chinese Eastern Railway running through his area of control.
