Joaquín Ibáñez Cuevas y de Valonga, 3rd Baron de Eroles and Marquis of Cañada Ibáñez was a Spanish nobleman and soldier, active in Catalonia during the Peninsular War. Shortly before his death, he was promoted to Captain general of the Army, Spain's highest military rank.

Captain General has been the highest rank in the Spanish Army since the 18th century. A five-star rank with NATO code OF-10, it is equivalent to a field marshal of the armies of numerous countries, a general of the Army of the United States, a captain general of the Spanish Navy (Armada Española) or a Captain general of the Air Force in the Spanish Air and Space Force (Ejército del Aire y del Espacio). A Captain General's insignia consists of two command sticks under five four-pointed stars below the Royal Crown.
