Horseshoe Bend, Shirehampton (grid reference ST542767) is an 11 acre (4.45 hectare) biological Site of Special Scientific Interest in Bristol, England, on the north bank of a lower, tidal stretch of the River Avon, 1.9 miles (3.1 kilometres) downstream from the Avon Gorge, and just east of Shirehampton.

The site's principal interest and the reason for its designation as an SSSI is the presence of a population of the True Service-tree (Sorbus domestica) growing on the cliffs.

The nationally scarce Large-leaved Lime (Tilia platyphyllos) also occurs, and herbs include Field Garlic (Allium oleraceum) and Pale St. John's-wort (Hypericum montanum).

There are however two nationally scarce vascular plant species here as well – Slender Hare's-ear (Bupleurum tenuissimum) and Long-stalked Orache (Atriplex longipes).

There was an adequate depth of water, as it was approaching high tide, but on the narrow channel through Horseshoe Bend she grounded on the outer bank.
