The 26th Division (Spanish: 26ª División) was a division of the Spanish Republican Army in the Spanish Civil War. It was formed in April 1937 in Aragon from the militarized Columna Durruti during the reorganization of the Spanish Republican Armed Forces. The 26th Division included the 119th, 120th and 121st mixed brigades throughout the Civil War. It fought in the Huesca Offensive, the Battle of Belchite, the Aragon Offensive and the Battle of the Segre. Finally it was disbanded in February 1939 after the withdrawal and rush to the border that followed the rebel Catalonia Offensive.
