Justus Doolittle (simplified Chinese: 卢公明; traditional Chinese: 盧公明; Pinyin: Lú Gōngmíng; Foochow Romanized: Lù Gŭng-mìng; June 23, 1824, Rutland, New York – June 15, 1880, Clinton, New York) was an American Board missionary to China.
Having deliberately chosen China as his field of labor, he sailed for Fuzhou with his wife soon after graduation, and arrived there on May 31.
In February, 1864, he left China for a visit to the United States on account of his health.
In 1872 he entered the service of the Presbyterian Board at Shanghai, but was soon compelled to return home disabled.
Thomson's photographs of this journey were published as Foochow and the River Min (1873), a total of 46 copies.
