Zhou Fohai (Chinese: 周佛海; pinyin: Zhōu Fóhǎi; Wade–Giles: Chou Fo-hai; Hepburn: Shū Futsukai; May 29, 1897 – February 28, 1948) was a Chinese politician and the second-in-command of the Executive Yuan in Wang Jingwei's collaborationist Reorganized National Government of the Republic of China during the Second Sino-Japanese War.

During his stay in Japan, he became attracted to Marxism, and on his return to China, became one of the founders of the Chinese Communist Party (CCP).

He was assigned as a secretary to the Public Relations Department of the central government, but maintained strong ties with the party's leftist clique, headed by Wang Jingwei and Liao Zhongkai.

After Wang Jingwei broke ranks with the Kuomintang during World War II and established the collaborationist Reorganized National Government of the Republic of China, Zhou soon followed.

Within the new government, Zhou became Vice President, Minister of Finance and had control over part of the Nanjing regime army.
