King's Highway 58, commonly referred to as Highway 58, is a provincially maintained highway in the Canadian province of Ontario. The route is divided into two segments with a combined length of 15.5 km (9.6 mi). The southern segment travels from Niagara Regional Road 3, formerly Highway 3, in Port Colborne, to the Highway 58A junction in the southern end of Welland, a distance of 7.2 km (4.5 mi). The northern segment begins at Highway 20 near Allanburg and travels north and west to a large junction with Highway 406 at the St. CatharinesThorold boundary, a distance of 8.3 km (5.2 mi). An 18.1 km (11.2 mi) gap separates the two segments within Welland and Pelham. The entire route is located within the Regional Municipality of Niagara.

The history of Highway 58 is tumultuous due to various relocation projects resulting from the construction of the fourth Welland Canal and Highway 406. Prior to 1997, Highway 58 was continuous and travelled through the west side of Welland, maintained under a Connecting Link agreement. The route was first established in 1935, though it remained unnumbered on the 1935 and 1936 official road maps. By 1937 it extended from Port Colborne to St. Catharines, though the route it travelled between those places shifted several times over the following 30 years. In the late 1990s, the Ministry of Transportation of Ontario (MTO) transferred several highways or portions of highways throughout the province to lower levels of government. Highway 58 was decommissioned through Welland on April 1, 1997.
