Red Hill Valley is a valley in eastern and south-eastern Hamilton, Ontario, Canada. The valley is named after and home to the Red Hill Creek, which flows 7 kilometres (4.3 mi) north-east from Albion Falls on the Niagara Escarpment, before bending north-west near the Queen Elizabeth Way and discharging into Hamilton Harbour at Windermere Basin. The name of the area comes from the reddish soil, rich with iron. The valley is estimated to be 1,600 acres (650 ha) in size. The Red Hill Valley was the site of a protracted battle over an expressway through the valley, ultimately constructed in 2007.
