Worcester Regional Airport (IATA: ORH, ICAO: KORH, FAA LID: ORH) is three miles (5 km) west of Worcester, in Worcester County, Massachusetts, United States. The main property lies within municipalities of Worcester and Leicester, with supporting facilities in Paxton. Once owned by the City of Worcester, the airport has been owned and operated by the Massachusetts Port Authority (Massport) since June 2010.

The airport code is believed to have originated from the word "Worcester". "W" cannot be used as the first letter of the identifier for airports in the United States, and "ORC" was already assigned. The origin of the "H" is unclear and might have been arbitrary.
