Ontario Highway 402, also called King's Highway 402, is a provincial highway in southwestern Ontario, Canada. It connects the Blue Water Bridge in Sarnia and Ontario Highway 401 in London. The highway runs mostly east-west. The only large municipality along the highway is Strathroy-Caradoc.

Construction on the highway started in 1939 but was stopped due to World War II. Work started again in 1952. The highway was finished in 1982. In 2009, the westbound part of the highway near Sarnia was widened from four lanes into six lanes.
