The ACS Style is a set of standards for writing documents relating to chemistry, including a standard method of citation in academic publications, developed by the American Chemical Society (ACS).

Previous editions of the ACS style manual are entitled ACS Style Guide: Effective Communication of Scientific Information, 3rd ed. (2006), edited by Anne M. Coghill and Lorrin R. Garson, and ACS Style Guide: A Manual for Authors and Editors (1997).

As of 2020, ACS style guidance and best practices for scholarly communication in the sciences are incorporated into the ACS Guide to Scholarly Communication, edited by Gregory M. Banik, Grace Baysinger, Prashant V. Kamat, and Norbert Pienta. The Guide is published online by ACS Publications.
