Francisco Coello de Portugal y Quesada (1822 - September 30, 1898) was a Spanish cartographer, explorer, and military engineer active in the mid-19th century. Coello was born in Jaen, Spain and joined the military in 1833, enrolling at the Special Army Corps of Engineers Academy of Guadalajara. Upon graduating with honors he joined Corps of Military Engineers where after serving in the First Carlist War, and later in Algeria, he attained the rank of Colonel. Coello later founded the Geographical Society of Madrid and served many years as its president. He was also a corresponding member of the American Geographical Society and a full member of the Real Sociedad Geográfica de España. Coello's greatest work, his monumental Atlas de España y sus posesiones de Ultramar, was truncated by his death in 1898 and consequently never completed. Nevertheless, the work is of historical significance as the first scientifically produced maps of Spain, Cuba, and Porto Rico.
