Newton St Loe SSSI (grid reference ST715657) is a geological Site of Special Scientific Interest (SSSI) close to the River Avon, near the village of Newton St Loe in Bath and North East Somerset.

The site was featured in the Geological Conservation Review.

The site is designated as an SSSI because it represents the only remaining known exposure of fossiliferous Pleistocene gravels along the River Avon.

In conjunction with other sites within the wider area, it has aided the development of a scientific understanding of the history of early glaciation within South West England.

It was not possible to identify the species however, due to the poor state of the specimens.
