King's Highway 98, commonly referred to as Highway 98, was a provincially maintained highway in the Canadian province of Ontario, designated as part of the provincial highway system between 1939 and 1971. The route travelled through the northern part of Essex County and through south-central Chatham-Kent, extending 96.3 kilometres (59.8 mi) from Windsor to Blenheim. Since 1998, it has been known as Essex County Road 46 between Windsor and Tilbury, and Chatham-Kent Road 8 between Tilbury and Blenheim.

Between Windsor and Tilbury, Highway 98 followed what was the original route of Highway 2, and later Highway 2A. After being assigned a unique route number in 1939, it was extended east to Blenheim in 1941. The purpose of Highway 98 within the provincial highway network was superseded by Highway 401, which was opened in sections between Windsor and London from 1957 to 1964. Consequently, it was transferred to Essex and Kent counties in 1970 and 1971.
