Operation Oyster was a bombing raid made by the Royal Air Force (RAF) on 6 December 1942 upon the Philips works at Eindhoven, Netherlands. The Philips company was a major producer of electronics equipment, including vacuum tubes for radio communication. Prior to the Battle of the Netherlands in 1940, Philips was known to be a leading research firm in infrared and radar technology. To ensure accuracy and minimise casualties among the Dutch citizens, the raid had to be undertaken during the day.

Koninklijke Philips N.V., commonly shortened to Philips, is a Dutch multinational conglomerate corporation that was founded in Eindhoven in 1891. Since 1997, its world headquarters have been situated in Amsterdam, though the Benelux headquarters is still in Eindhoven. Philips was formerly one of the largest electronics companies in the world, but is currently focused on the area of health technology, having divested its other divisions.
