Historically, in the Civil Police of Portugal, a police commissioner () was a divisional commander in the Lisbon and Oporto police forces or the chief of a district police force in the other districts of the country. The chief of each of the Lisbon and Oporto police forces had the title of "commissioner general" ("comissário-geral"). With the reorganization of Civil Police and its transformation in the Public Security Police (PSP) in the 1930s, commissioner became a police rank in this force.
