Sockburn is an industrial suburb of Christchurch, New Zealand, located between Hornby and Riccarton, some 7 kilometres (4.3 mi) west of the Christchurch city centre. The suburb is roughly bounded by the triangle formed by State Highway 1 in the west, Main South Road (SH73a) in the south and SH73 in the north. The suburb of Wigram, containing the city's former RNZAF base (now an aviation museum), is located nearby. One of the city's main horseracing circuits, Riccarton Racecourse, is located close to Sockburn's northern edge, and Racecourse was the initial name for the area. The name Sockburn is likely to have come from the village of Sockburn in County Durham, England.
