The American Journal of Science (AJS) is the United States of America's longest-running scientific journal, having been published continuously{{Citation needed|date=November 2024}} since its conception in 1818 by Professor Benjamin Silliman,{{Cite web |date=2024-11-21 |title=Benjamin Silliman |url=https://www.britannica.com/biography/Benjamin-Silliman-American-geologist-and-chemist-1779-1864#ref252749 |access-date=2024-11-29 |website=Britannica |language=en}} who edited and financed it himself.{{Citation needed|date=November 2024}} It was initially called the American Journal of Science and Arts until a name change in 1880,{{Citation needed|date=November 2024}} but its focus was always on natural sciences and especially on geology and related subjects.{{Citation needed|date=November 2024}}

In early years, the journal was often referred to as "Silliman's Journal", and the publication became associated with Yale University due to his long tenure there (1804–1853).{{Citation needed|date=November 2024}} The editorship long remained in the family of Professor Silliman, as he was assisted by his son, Benjamin Silliman Jr., from 1838. On the death of the elder Silliman in 1864, he was succeeded as chief editor by his son-in-law, James Dwight Dana, and then from 1895 till 1926 by Dana's son Edward Salisbury Dana. Associate editors included the botanist Asa Gray and the zoologist Louis Agassiz.

The current editors are Mark T. Brandon, professor at Yale University, C. Page Chamberlain, professor at Stanford University, Francis Macdonald UC Berkeley, and Ann Pearson Harvard University.
