美国微生物学会（英语：American Society for Microbiology，缩写ASM，曾称为美国细菌学会，英语：Society of American Bacteriologists）是一个美国微生物学科学组织，致力于推广这些肉眼不可见的有机体的研究。ASM的会员科学家的研究领域囊括了从基础的微生物生理生化到应用的微生物相关疾病等微生物学各个领域。

The American Society for Microbiology (ASM), originally the Society of American Bacteriologists, is a professional organization for scientists who study viruses, bacteria, fungi, algae, and protozoa as well as other aspects of microbiology. Microbiology is the study of organisms too small to be seen with the naked eye and which must be viewed with a microscope. ASM membership includes scientists who do basic research into the nature and lives of viruses, bacteria, and other microorganisms. ASM membership also includes scientists who work in the field of applied microbiology, for example, researching cures for diseases caused by microorganisms, or the potential for microorganisms to create cheeses from milk, to generate fuels, or to clean up oil spills.
