King's Highway 405, also known as Highway 405 and the General Brock Parkway, is a 400-Series Highway in the Canadian province of Ontario connecting the Queen Elizabeth Way (QEW) near St. Catharines with the Lewiston–Queenston Bridge in the village of Queenston. It then crosses the Niagara River, where it encounters the international border with the United States and continues into New York as Interstate 190 (I-190).

Designated and under construction by 1960, the short freeway was opened to traffic on September 11, 1963. Since that time, an interchange was added in 1969 and another removed in 2004. On August 13, 2006, Highway 405 was dedicated the General Brock Parkway. The entire length of Highway 405 is patrolled by the Ontario Provincial Police (OPP).

Highway 405 serves to connect the northern end of I-190 in New York at the Lewiston–Queenston Bridge with the QEW, and as such it follows a somewhat direct path between the two. Throughout its length, the highway gently climbs the Niagara Escarpment, reaching the top east of Stanley Avenue before crossing the Niagara Gorge. The highway is surrounded by forest to either side for most of its length, and the only settlement near it is the village of Queenston.
