The Melbourne Formation is a geologic formation in Victoria, Australia. It preserves fossils dating back to the Ludlow epoch of the Silurian period.
Description
The Melbourne Formation, part of the Murrindindi Supergroup, is conformably overlain by the Humevale Formation and overlies the Yan Yean and Anderson Creek Formations. The formation comprises mainly thin-bedded siltstone and sandstones. Most beds show undisturbed Bouma sequences.

The following fossils were reported from the formation:
Eurypterids
Trilobites
Brachiopods
Gastropods
Bivalves
Scyphozoa
Corals
Ophiuroidea
Crinoids
