AccuWeather is an American media company that provides for-profit weather forecasting services worldwide. The name AccuWeather is a portmanteau of the words "accurate" and "weather".

AccuWeather was founded in 1962 by Joel N. Myers, then a Penn State graduate student working on degrees in meteorology. His first customer was a gas company in Pennsylvania. While running the company, Myers also became a member of Penn State's meteorology faculty. The company adopted the name "AccuWeather" in 1971.

AccuWeather is headquartered in State College, Pennsylvania, with sales offices in Rockefeller Center in New York City and Fort Washington, Pennsylvania. In 2006, AccuWeather acquired WeatherData, Inc. of Wichita, Kansas. As WeatherData Services, Inc., an AccuWeather Company, the Wichita facility now houses AccuWeather’s specialized severe weather forecasters.

AccuWeather markets weather products and services, with 175,000 clients worldwide in media, business and government. It also runs the free, advertising-supported website AccuWeather.com, an online weather provider. The company claims that the AccuWeather brand and weather are presented to over 110 million people every day. AccuWeather employs 404 persons, of whom 113 are meteorologists.
