The Williams FW04 (later the Wolf–Williams FW04) was a Formula One car used by Frank Williams Racing Cars during the 1975 season and Wolf–Williams Racing during the 1976 season. The car was a development of the Williams FW and two were built. Although not a particularly successful car, an FW04 finished second at the 1975 German Grand Prix.
