Thicket Burn Campsite is a free DOC basic campsite situated within Fiordland National Park in southern New Zealand, roughly 25 kilometres west of Clifden via Lillburn Valley Road.

Access is along a long gravel road, making it a somewhat remote destination, but one that rewards visitors with a quiet, scenic setting.

The campsite accommodates up to 20 tent sites and provides basic facilities including toilets, picnic benches, and a designated fireplace (subject to fire bans).

It sits approximately 5 kilometres from Lake Hauroko, New Zealand's deepest lake, with opportunities for fishing, swimming, and tramping in the surrounding Fiordland wilderness.
