Sebastián Pozas Perea (Zaragoza, 1876 – 1946) was a Spanish military officer and civil servant.

Trained in the cavalry, Pozas undertook extended service in Spanish Morocco, fighting in the Rif Wars and attaining the rank of general in 1926, by order of the Miguel Primo de Rivera government.

[1] When the Nationalists rose against the government on June 18, 1936, leading to the Spanish Civil War, Pozas remained loyal and rallied large numbers of police and paramilitary units to the Republic.

Pozas briefly served as Minister of the Interior[3] before being put in command of the Army of the Center,[4] in October 1936.

[5] Nearly overwhelmed along the Jarama in February 1937,[6] the Army of the Centre ultimately flung back the Nationalist pincers closing around Madrid after a bloody campaign culminating in the Battle of Guadalajara.
