Te Rere o Ōmanawa — meaning "the waterfall of the heart" — is a striking waterfall on the Ōmanawa River in the Bay of Plenty region of New Zealand's North Island, about 20 minutes from Tauranga via State Highway 29.

The site holds deep significance for local hapū Ngāti Hangarau, for whom it has long been a place of āio (reflection and insight) and rongoā (meditation and healing). Swimming is not permitted out of respect for this sacred status.

Following cliff-reinforcement work and the construction of new walking tracks, the reserve is now open to the public. Visitors can reach viewpoints including the Wairere Tapu Lookout, with a longer route continuing to a final lookout via roughly 700 steps.

The site also features the Ōmanawa Falls Power Station, recognized as the first underground hydro-generating power station in New Zealand.
