Gaius Octavius Tidius Tossianus Lucius Javolenus Priscus was a Roman senator and jurist who flourished during the Flavian dynasty.

Priscus served as suffect consul for the nundinium (period) September to December 86 AD as the colleague of Aulus Bucius Lappius Maximus.

[3] Anthony Birley notes that his names "Javolenus, Tidius, and Tossianus all point to Umbria, and specifically Iguvium as the origo of Priscus.

"[4] However Birley points to Géza Alföldy's argument that he ought to be connected with the Octavii of Nedium in Dalmatia where Javolenus Priscus had been honored.

"[2] There is no historical record of Javolenus Priscus prior to his taking command of Legio IV Flavia Felix, stationed near Burnum, in modern Croatia; it may be he was adlected into the Senate inter praetorios.
