King's Highway 107, commonly referred to as Highway 107, was a provincially maintained highway in the Canadian province of Ontario situated midway between the towns of Kingsville and Leamington. The route was one of the shortest highways to exist in the province, at a length of 1.5 kilometres (0.93 mi). It has been through several re-numberings throughout its history but is now known as Essex County Road 45 or Union Avenue. The route began at Highway 18 and travelled north to Highway 3 at Ruthven.

Highway 107 was known as Highway 18B from 1937 until 1952. It was decommissioned in 1970, but was later briefly assigned as the eastern leg of Highway 18 in 1997. The highway was once again decommissioned in 1998. Since then, as well as between 1970 and 1997, the route has been known as Essex County Road 45.
