The National Institutes of Health is an institution of the United States government which focuses on medical research. The Institutes are located in Bethesda, Maryland.

The predecessor of the National Institutes of Health (NIH) began in 1887 as the Laboratory of Hygiene. It was grew and was reorganized in 1930 by the Ransdell Act into the National Institutes of Health. Today it is one of the world's foremost medical research centers, and the Federal focal point for medical research in the U.S. The NIH, headed by the Office of the Director and comprising 27 separate Institutes and Centers, is one of eight health agencies of the Public Health Service which, in turn, is part of the United States Department of Health and Human Services. The current NIH Director is Elias Zerhouni.

Simply described, the goal of NIH research is to acquire new knowledge to help prevent, detect, diagnose, and treat disease and disability, from the rarest genetic disorder to the common cold. The NIH mission is to uncover new knowledge that will lead to better health for everyone. NIH works toward that mission by: conducting research in its own laboratories; supporting the research of non-Federal scientists in universities, medical schools, hospitals, and research institutions throughout the country and abroad; helping in the training of research investigators; and fostering communication of medical and health sciences information.
