Quintus Vibius Secundus was a Roman Senator who was active during the reigns of Domitian and Trajan. He was suffect consul for the nundinium of March to April 86.
A member of the gens Vibia, Secundus is considered to be the son of the influential Politician Lucius Junius Quintus Vibius Crispus. There is a possibility that Secundus could be related to suffect consul Lucius Vibius Sabinus, father of the Empress Vibia Sabina.
Only one office is known for Secundus: in 101/102 the sortition selected him as proconsular governor of Asia.
