Charles Hartwell (Chinese: 夏察理; Pinyin: Xià Chálǐ; Foochow Romanized: Hâ Chák-lī; December 19, 1825 - January 30, 1905) was an American Board missionary to Fuzhou, China in the second half of the 19th century.

After teaching several months at West Killingly, Hartwell studied theology at Amherst College in 1849, and received the degree of Master of Arts from the same institution three years later.

He was ordained at Lincoln, Massachusetts, on October 13, 1852, entered the service of the ABCFM, embarked for China on November 3, and reached Hong Kong on April 16, 1853.

He also prepared many textbooks for schools (including one series of the so-called Hongkong Readers), wrote a book on Meteorology, and contributed articles on temperance to English and American journals.

The fiftieth anniversary of Hartwell's arrival at Fuzhou was celebrated on May 26, 1903, a full account of which was issued from the Foochow Mission Press in February, 1904, in a volume entitled Jubilee Notes.
