Hornby is a major residential and retail suburb at the western edge of Christchurch, New Zealand. It is located on an important road junction connecting State Highways 1 and 73A at the start of the central Christchurch by-pass. To the west, State Highway 1 continues, gradually veering southward on its passage to Dunedin and other points south.
Hornby contains a large retail mall named 'The Hub Hornby' which is the westernmost within the Christchurch urban area. The suburb - which could almost be considered a town in its own right - is separated from the heart of the city by Wigram aerodrome and the industrial estates of Sockburn to the east. Hornby is home to a velodrome and a BMX track. It has annually hosted the "Westside Party in the Park" for the last several years.
The Hornby area contains seven schools: South Hornby Primary, Hornby Primary, Gilberthorpes Primary, Sockburn Primary, St. Bernadettes, Branston Intermediate and Hornby High School
