"Serve the People" or "Service for the People" (simplified Chinese: 为人民服务; pinyin: wèi rénmín fúwù) is a political slogan which first appeared in Mao-era China. It originates from the title of a speech by Mao Zedong, delivered on September 8, 1944. The slogan was also widely used in the United States by students and youth during the Asian American movement of the late 1960's and 1970's. The slogan was very popular due the strong Maoist influence on the New Left, considerably amongst the Red Guard Party, the Black Panther Party, and the Yellow Brotherhood of West Los Angeles.

Mao Zedong wrote this speech to commemorate the death of a PLA Soldier, Zhang Side, a participant in the Long March who died in the collapse of a kiln. In the speech he quoted a phrase written by the famous Han Dynasty historian Sima Qian, "Though death befalls all men alike, it may be weightier than Mount Tai or lighter than a feather." (“人固有一死，或重于泰山，或轻于鸿毛。”). Mao continued: "To die for the people is weightier than Mount Tai, but to work for the fascists and die for the exploiters and oppressors is lighter than a feather. Comrade Zhang Side died for the people, and his death is indeed weightier than Mount Tai."

The concept of "Serving the People", together with other slogans such as "Never benefit oneself, always benefit others" and "Tireless struggle" became core principles of the Communist Party of China
