The American Physical Society (APS) is the professional organization for physicists in the United States. They raise funds and are active in lobbying Congress and other government officials for scientific funding. The Society is active in helping physics graduates find employment.

Examples of APS publications are the research journals, Physical Review and Reviews of Modern Physics, as well as a more accessible magazine called Physics Today. Many conferences in the U.S. are also sponsored by the APS. Of particular importance are the national "March" and "April" meetings, the former focuses on condensed matter and applied physics, while the latter is more oriented toward nuclear physics. The Division of Particles and Fields (DPF) also holds a national meeting.

The American Physical Society is one of five members of the American Institute of Physics.
