Sicko or SiCKO (2007) is an Academy Award nominated documentary film by American filmmaker Michael Moore that investigates the American health care system, focusing on its for-profit health insurance and pharmaceutical industry. The film compares the non-universal and for-profit U.S. system with the universal and non-profit systems of Canada, the United Kingdom, France and Cuba.

Sicko opened to positive reviews, but also generated criticism and controversy. Some policy specialists have praised the film while others have criticised the film for its positive portrayal of the publicly funded health systems of Canada, the United Kingdom and Cuba, and for its negative portrayal of the health care system in the United States.

Sicko opened in the U.S. exclusively on a single screen at the AMC Lincoln Square theater in Manhattan the weekend of June 22–24, 2007, earning $68,969 per screen, then opened nationwide the weekend of June 29–July 1, 2007, earning $4,501,712 in 441 theaters and achieving the second highest nationwide opening weekend for a documentary, after Fahrenheit 9/11.

Documentary look at health care in the United States as provided by profit-oriented health maintenance organizations (HMOs) compared to free, universal care in Canada, the U.K., and France. Moore contrasts U.S. media reports on Canadian care with the experiences of Canadians in hospitals and clinics there. He interviews patients and doctors in the U.K. about cost, quality, and salaries. He examines why Nixon promoted HMOs in 1971, and why the Clintons' reform effort failed in the 1990s. He talks to U.S. ex-pats in Paris about French services, and he takes three 9/11 clean-up volunteers, who developed respiratory problems, to Cuba for care. He asks of Americans, "Who are we?"
