Juan Yagüe Blanco (Spain, 1891 - October 29, 1952) was a Spanish Army Officer during the Spanish Civil War.

The son of a doctor, he enrolled at a young age in the Infantry Academy of Toledo, where Francisco Franco was a fellow cadet. The two men received their commissions concurrently and served together in Africa, where Yagüe was wounded on several occasions and received several decorations.

Yagüe was promoted to lieutenant colonel in 1932. He, along with Franco and General López Ochoa, helped suppress a workers uprising in Asturias using African Regulars and Legionnaires in 1934. He was an strong early supporter of the Falange Española and close personal friend of José Antonio Primo de Rivera.

When Niceto Alcalá-Zamora was replaced as President of the Republic by the left-wing Manuel Azaña on May 10, 1936, a group of Spanish Army officers, including Yagüe, Emilio Mola, Francisco Franco, Gonzalo Queipo de Llano and José Sanjurjo, started plotting to overthrow the Popular Front government. This led to a military uprising which precipitated the Spanish Civil War on July 17, 1936.

Yagüe's forces revolted in Ceuta before crossing the Straits of Gibraltar to link up with Nationalist forces in Seville, led by Queipo de Llano. Yagüe advanced northward, first seizing Merida before attacking Badajoz with 3,000 troops on August 14, 1936. Bitter street fighting took place when the Nationalists advanced into the city. Yagüe's forces gained control of Badajoz, with both sides suffering heavy casualties.

Yagüe, promoted to colonel, afterwards advanced on Madrid, capturing Trujillo, Navalmoral de la Mata and Talavera de la Reina, but was unable to take the capital. He took part in the Aragón offensive and seized control of Belchite, Caspe and Lérida. He also played a leading role in the Nationalist victory at the Battle of the Ebro. After the collapse of the Republic in 1939, Yagüe was promoted to major general and appointed as Minister of Air by General Franco. He was made a lieutenant general in 1942 and was posthumously made commander in chief upon his death.
