Erastus Wentworth (simplified Chinese: 万为; traditional Chinese: 萬為;[1] Pinyin: Wànwéi; Foochow Romanized: Uâng-ùi; August 5, 1813 – May 26, 1886) was an educator, a Methodist Episcopal minister, and a missionary to Fuzhou, China.

Later he studied at the Cazenovia Seminary and earned a bachelor's degree at Wesleyan University in 1837.

[2] In 1854, Dr. Wentworth left his position to spearhead a Methodist Mission to Fuzhou, China, along with some students who were just graduating from Dickinson, including Otis T. Gibson.

In 1862, his wife's poor health forced him to return to the United States, where he then worked as a pastor to the Troy Conference Academy.

Wentworth edited the Ladies' Repository from 1872–76, after which he semi-retired, writing and serving on committees for the Methodist Church.
