Shallow Inlet is a marine inlet, opening onto Waratah Bay on the western side of the Yanakie Isthmus in South Gippsland, Victoria, south-eastern Australia.

The inlet is a shallow, curving, 18 km2 tidal embayment with a single channel to the sea.

On the seaward side it is enclosed by a barrier of sandy spits, bars and mobile dunes.

The extensive intertidal mudflats and areas of sand provide habitat for waders, or shorebirds.

[2] The inlet has been identified by BirdLife International as an Important Bird Area (IBA) because it supports over 1% of the world populations of double-banded plovers and red-necked stints, and has supported the critically endangered orange-bellied parrot.
