ACA is an acronym that can refer to several unrelated laws, organizations, and programs. The most widely known is the Affordable Care Act, a United States health care reform law enacted in 2010 to expand health insurance coverage and implement various health care system changes.

The acronym is also used by professional associations, including the American Counseling Association, the American Chiropractic Association, and the American Canoe Association. The American Counseling Association is a national organization serving counselors across settings and focusing on professional ethics, training, and advocacy. The American Chiropractic Association represents chiropractors and promotes standards of practice and public education about spinal health. The American Canoe Association is a nonprofit that promotes paddling and safety through programs, events, and certifications.

In addition to these groups, ACA may stand for other entities such as regional government programs, corporate bodies, or academic initiatives, depending on the context. Because ACA is a common acronym, its exact meaning is usually determined by surrounding text or a definitional note. When encountering the acronym, readers should seek clarification to identify the intended referent.
