José López Domínguez (29 November 1829, in Marbella – 17 October 1911, in Madrid), was a Spanish military officer and politician who was prime minister of Spain between 6 July and 30 November 1906.
In 1871, he became mariscal de campo and personal military advisor to King Amadeo I of Spain. In 1873, he was appointed commander of the Army of the North against the Carlists in the Third Carlist War, but in the same year, he was asked by Emilio Castelar to lay siege to Cartagena, where the Cantonal Revolution had broken out. He had the city intensively bombarded and, on 12 January 1874, Cartagena was retaken. He then returned to the north and liberated Bilbao, which was under siege by the Carlists.
In 1883, he was minister of war in the Posada Herrera government and, between 1892 and 1895, in the Sagasta government.
During the Second Melillan campaign, he became captain-general and was also the representative of Malaga in the Spanish senate, a chamber of which he became the president between 1905 and 1907.
In July 1906, aged 77, he became prime minister of Spain with a government supported by José Canalejas. In the first months, he was also minister of war. After a plot within his own party, led by Segismundo Moret, he was forced to resign after five months. After his resignation, he retired from politics
