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).

This article has multiple issues. Please help improve it or discuss these issues on the talk page. (Learn how and when to remove these template messages) This article includes a list of references, related reading, or external links, but its sources remain unclear because it lacks inline citations. (March 2017) This article relies largely or entirely on a single source. (March 2017) The topic of this article may not meet Wikipedia's general notability guideline. (July 2019)

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.
