Nathan Sites (Chinese: 薛承恩; Pinyin: Xuē Chéng'ēn; Foochow Romanized: Siék Sìng-ŏng; November 6, 1830 – February 10, 1895) was a 19th-century Methodist Episcopal missionary who served in Fuzhou and Yanping (now Nanping), Fujian Province, China.

In 1861, he reached Fuzhou with his wife Sarah Moore Sites to begin his oversea missionary work which would last until his death in 1895.

Upon his arrival, Sites chose to live in a countryside hamlet among native villagers to experience the rural life of the Chinese.

During his missionary life in China, Sites met with many obstacles: one day while carrying out the reconstruction work of the local church in Yanping, he was brutally beaten by an enraged mob, who left a deep scar on his face.

Like other missionaries, Sites argued and labored for the creation of a strong and independent Chinese Church, and in this effort he ordained many of the earliest native Christian ministers like Sia Sek Ong, Wong Nai Siong and the father of Hü King Eng.
