Mercer's tusked silverside (Dentatherina merceri) is a species of fish.

Mercer's tusked silverside originates from the west-central Pacific.

It is found from the Philippines to north-eastern Australia and from Moluccas to the Trobriand Islands.

The distinctiveness of Dentatherina could be used in favor of separate family recognition.

[2] Fish Base considers this species to belong to its own family.
