Trevorite is a rare nickel iron oxide mineral belonging to the spinel group.

It was first described for an occurrence in the Bon Accord Nickel Deposit, Bon Accord, Barberton, Mpumalanga, South Africa, in 1921 and was named for Major Tudor Gryffydd Trevor (1865–1954) who was a mining inspector in South Africa.

In an occurrence at Mount Clifford, Australia, it occurs associated with a nickel sulfide orebody adjacent to a gabbro which intruded peridotite.

Associated minerals include nimite, willemseite, nickeloan talc, violarite, millerite, reevesite and goethite at Bon Accord; and with native nickel, heazlewoodite and millerite at Mt.

[2] It has also been reported from the Logatchev-1 hydrothermal field on the Mid-Atlantic Ridge; in the Hatrurim Formation in the Negev Desert in Israel; the Josephine Creek District, Josephine County, Oregon and the Gabbs District of Nye County, Nevada.
