Secondary Highway 664, commonly referred to as Highway 664, is a secondary highway in the Canadian province of Ontario. Located in Kenora District, the highway links the community of Hudson to Highway 72 near Sioux Lookout. In late July 2012, it was announced that the road would be renamed The Leo Bernier Memorial Highway, after the former MPP for Kenora and Minister of Northern Affairs.^[15]

The highway began as a part of Highway 72 in 1934. In 1954, the road was renumbered as Highway 116, but may have been briefly designated as "Highway 72A" before that. By 1975, the Ministry of Transportation of Ontario had decided to demote three very lightly travelled Kings Highways in Northwestern Ontario to secondary highway status. Those roadways were Highway 116 (which became Highway 664), Highway 119 (which became Highway 665), and Highway 128 (which became the infamous Highway 666, and was consequently renumbered as Highway 658 in 1985.)

The road today is a typical secondary highway: lightly travelled, connecting a town to a main Kings Highway (Highway 72), and has slightly narrower and coarser pavement than Kings Highways.
