Glenbrook is a rural and industrial area in the Auckland region of New Zealand. The industrial area, that of New Zealand's major steel mill, New Zealand Steel, is not located close to any towns - the surrounding countryside is occupied by farms. The nearest towns are Waiuku, five kilometres to the south, and Pukekohe, 15 kilometres to the east.

Glenbrook's other claim to fame is the Glenbrook Vintage Railway.
