Champion is an American brand of spark plug. Originally Champion was a Fortune 500 Company founded by Robert A. Stranahan and Frank D. Stranahan in 1908 in Boston and then moved to Toledo, Ohio in 1910 to be close to the Willys-Overland Auto Company.

In 1989, Champion was purchased by Cooper Industries and is now a wholly owned brand of Federal-Mogul Corporation. Its main products are a line of spark plugs for a wide range of cars, trucks, SUVs, racing and marine applications. Also included in the brand are spark plug wires and other ignition system specific wiring.

Champion is also a longtime sponsor of various racing events, cars, and series including two series run under sanctioning by IMSA.
