Caleb Cook Baldwin (1820 - July 20, 1911; Chinese: 摩憐 or 摩嘉立; Pinyin: Mólián, Mó Jiālì; Foochow Romanized: Mò̤-lèng, Mò̤ Gă-lĭk) was one of the first Congregationalist missionaries to Fuzhou, China.

Baldwin graduated from Princeton Theological Seminary in 1847 and was ordained as an Evangelist in the Old Presbyterian Church in Bloomfield.

The Baldwins learned the native language and were responsible for extensive work in literacy, education and evangelistic departments.

Founding schools and superintending them in cities and villages, the Baldwins traveled by boats, sedans and the most primitive locomotion.

In connection with his wife he also translated much of the Bible into Fuzhou dialect and prepared text-books such as Catechism of Christian Doctrine (聖學問答).
