a Roman jurist, quoted in the Digest, once by Valens (Dig. 38, tit. 1, s. 47), and once by Pomponius. (Dig. 40, tit. 5, s. 34.1.) As both Valens and Pomponius lived about the time of Hadrian and Antoninus Pius, Campanus probably flourished about the commencement of the second century. Both the passages quoted from him relate to fideicommissa.

A Cocceius Campanus, to whom was addressed a rescript of the emperors Severus and Antoninus (Dig. 36, tit. 1, s. 29), must have been of later date, though he is confounded with the jurist by Bertrandus. (Menag. Amoen. Jur. 100.38; Maiansius, ad 30 JCtos, ii p. 197.)
