Francisco Coello de Portugal y Quesada (1822-1898) was a Spanish cartographer and military professional who authored an atlas of Spanish possessions overseas, published in Madrid between 1848 and 1869. The atlas was created as an accompaniment to the Diccionario Geografico Estadistico Historico by Pascual Madoz. Although 65 maps were originally planned, only 45 maps were eventually completed. Coello studied at the Academia de Ingenieros de Guadalajara (Academy of Engineering in Guadalajara) and was assigned as Lieutenant Colonel of the Spanish Corps of Engineers and stationed in Algeria in 1844. Coello founded the Sociedad Geografica de Madrid (Geographical Society of Madrid) in 1876, which later became the Real Sociedad Geografica de Espana (Royal Geographical Society of Spain).
