Elizabeth Grant Falls is a dramatic waterfall on Koolmoon Creek in the Misty Mountains area of the Atherton Tablelands, Queensland. The falls cascade roughly 300 metres in total over a series of drops, culminating in a final plunge of approximately 90 metres.

Because Koolmoon Creek is perennial, the falls run year-round, though they are most impressive after rain. Even at the end of the dry season, when water levels are at their lowest, the falls remain a striking sight.

The falls are reached via a signed track from a campground, branching off the Koolmoon Creek track at around the 3-kilometre mark and continuing a further 2. 2 kilometres to a lookout.

The track ends at a small clearing where a gap in the trees frames a spectacular view of the falls. The base of the falls is not accessible from the lookout trail.
