The U.S. Army Pikes Peak Research Laboratory, or simply the "Pikes Peak Lab", is a modern medical research laboratory for the assessment of the impact of high altitude on human physiological and medical parameters of military interest. It is a satellite facility of the U.S. Army Research Institute of Environmental Medicine (USARIEM), located in Natick, Massachusetts.
