Hooker Glacier is one of several glaciers close to the slopes of Aoraki/Mount Cook in the Southern Alps of New Zealand. It is not as large as its neighbour, the Tasman Glacier, measuring 11 kilometres (roughly 6–7 miles) in length. It is on the southwestern slopes of Aoraki/Mt Cook, and is the source of the Hooker River, a small tributary of the Tasman River, which flows into Lake Pukaki. One of New Zealand's more accessible glaciers, it can be seen clearly from the end of the Hooker Valley Track, close to The Hermitage.
