Middleton is a predominantly industrial and wholesale suburb of Christchurch, New Zealand.

[3] It is located in the west of the city, between Wigram and Addington, and immediately to the south of Upper Riccarton.

Middleton's boundaries are typically defined by major roads.

Blenheim Road, a major Christchurch thoroughfare with multiple retail and commercial premises, forms much of the northern limit, while Matipo Street generally defines the eastern boundary, with Addington Raceway and Horncastle Arena just beyond in neighbouring Addington.

The suburb is also home to a large rail yard operated by KiwiRail, connecting Christchurch to both the South Island Main Trunk Railway and the Midland Line.
