American Cyanamid was a large, diversified, American chemical manufacturer. Lederle Laboratories was Cyanamid's pharmaceutical division.

In its later life, the company frequently brushed up against the law for its environmental practices. In the process, it abandoned a number of hazardous waste sites to the government, notably the Bound Brook and Bridgewater sites in New Jersey.

Portions of the company have been spun off to American Home Products (1994, now Wyeth) and BASF (2000).
