was one of the three commissioners appointed in the reign of Nero, A. D. 61, to take the census of the Gauls. He was consul suffectus in the following year (A. C.). 62) with L. Annaeus Seneca; and accordingly a Senatusconsultum passed in their consulship is quoted under the title of Senatusconsultum Trebellianum. (Gaius, 2.251, 253; Dig. 36. tit. 1.)

Trebellius afterwards succeeded Petronius Turpilianus in the government of Britain, where he was hated by the army on account of his inactivity, pusillanimity, and avarice. In the commotions which followed the death of Nero, Roscius Caelius, the legate of Trebellius, induced the soldiers to rise against their general. Trebellius quitted the island, and fled to Vitellius. The latter, however, did not replace Trebellius in the government, but sent Vettius Bolanus to occupy the vacant post. (Tac. Ann. 14.46, Hist. 1.60, 2.65, Agr. 16.)
