King's Highway 78, commonly referred to as Highway 78, was a provincially maintained highway in the Canadian province of Ontario. The 17.60-kilometre (10.94 mi) route connected Highway 40 (McNaughton Avenue) in downtown Wallaceburg with Highway 21 (St. George Street) in Dresden.

Highway 78 was established in May 1938, and generally followed the same route throughout its existence; the majority of changes occurred within Wallaceburg. In 1962 the route was almost moved to follow Kent County Road 15 (Baseline Road), but local opposition cancelled the proposal. During the mid-to-late 1960s it was signed concurrently with Highway 21 between Dresden and Thamesville. Responsibility for maintenance of the entire route was transferred to the municipality of Chatham-Kent on January 1, 1998. Since then, it has been known as Chatham-Kent Road 78.
