Quintus Julius Cordinus Gaius Rutilius Gallicus was a Roman senator who held several posts in the emperor's service.

Gallicus held a series of further civic and military positions, including three governorships, pontifex, and urban prefect of Rome.

[3] J. E. H. Spaul suggested his birth father was Gaius Rutilius Secundus, equestrian governor of Mauretania Tingitana during the reign of the emperor Claudius.

The consulship was considered the highest honour the Roman state could bestow, and Vespasian would have made such appointments carefully, to reward loyalty and to consolidate support.

[10] Although being proconsul of Africa or Asia was considered a senator's highest and usually the final step in imperial service, Gallicus is known to have been Governor of Germania Inferior from 76 to 78.
