Amos Chafee Barstow (April 30, 1813 – September 5, 1894) was an American politician and businessperson.

[2] In 1851 Barstow was elected to the Rhode Island General Assembly, and on January 27, 1852, Barstow delivered a prominent speech to the Rhode Island House of Representatives in favor of Rhode Island's Maine law, which was one of the early temperance bills in the United States (so named because it was modeled after an 1851 temperance law in Maine).

Barstow was chairman of the committee which planned the current Providence City Hall.

[1][2][3] He also became active in the abolition movement, and gave various speeches predicting the end of slavery.

[3] In 1875, President Grant appointed Barstow to the Board of Indian Commissioners, and he spent much of his time visiting the American West.
