Light pollution (also known as photopollution, luminous pollution) is excess or obtrusive light created by humans. Among other effects, it can obscure all but a few stars to city dwellers, cause problems for astronomical observatories, and disrupt ecosystems. Since the early 1980s, a global dark-sky movement has emerged, with concerned people campaigning to reduce the amount of light pollution.

Light pollution is a side effect of industrial civilization. It comes from sources such as domestic lighting, advertising, commercial properties, offices, factories, streetlights, and lit sporting venues. It is most severe in the highly industrialised, densely populated areas of the United States, Europe, and Japan, but even relatively small amounts of light can be noticed and create problems.
