The red triangle slug, scientific name Triboniophorus graeffei, is a species of large air-breathing land slug, a terrestrial pulmonate gastropod mollusk in the family Athoracophoridae, the leaf-veined slugs.

This large (up to 15 cm), often colorful and striking-looking species is found in eastern Australia. It is Australia's largest native land slug. It is a common part of the fauna.

Triboniophorus graeffei is the type species of the genus Triboniophorus. A closely related species is the as-yet-unnamed Triboniophorus aff. graeffei.

This slug species occurs on the east coast of Australia, from New South Wales to Queensland.

A bright pink variation, Triboniophorus aff. graeffei, are found exclusively on Mount Kaputar.

Solem (1959) mentioned a possible introduction of this species to the New Hebrides, but no material was available to confirm it.

Red triangle slugs are found in damp situations in various habitats, including city gardens, forests, woodland and heaths.

These slugs graze on algae which grows on the surface of the smooth bark of some eucalyptus trees and on rocks. Sometimes the slugs enter houses and have been known to graze on the mold that grows on bathroom walls.
