Coronel Portillo is the second largest of four provinces in the Ucayali Region in Peru.

The province was created in 1943 within the jurisdiction of the Department of Loreto and initially covered the entire current territory of the Department of Ucayali.

The first mayor was Arturo Bartra Flores, who was directly appointed by national authorities due to his notable status as a resident, impeccable conduct, and initiatives for the economic, civic, and social progress of the province.

His leadership in municipal administration was limited to the year 1945.
