Millstream is a rural locality in the Tablelands Region, Queensland, Australia.

Their confluence which creates the Herbert River is just to the south-west of the locality in neighbouring Innot Hot Springs.

[3] Smaller farm blocks are found in the southern part of the locality, just to the north of The Millstream, where the land is flatter (about 730 metres above sea level).

However, much of the locality is mountainous, rising to unnamed peaks of about 1000 metres above sea level); this area is not developed.

[3] The Kennedy Highway passes through the locality from east to west.
