Carlos Rein Segura, OLSM (18 July 1897 – 11 February 1992) was a Spanish politician who served as Minister of Agriculture during the Francoist regime, from 1945 to 1951.

He carried out functions in the Board of Colonization and Interior Repopulation, serving in the agricultural colonies of the Galleon, in Cazalla de la Sierra and Cañamero.

Later he held another political position, that of president of the Partial Committee of Charter and Unloading of the Port of Málaga.

At the outbreak of the Spanish Civil War, he was deposed, detained and imprisoned on the Marqués de Chávarri prison ship, where he remained until February 8, 1937, when Málaga was taken by the Francoist army.

The intervention of the Consul of Mexico in Málaga, taking an interest in his situation and that of other political prisoners, allowed him to delay looking at his cause and saving his life.

The new authorities appointed him manager of the first Town Hall, president of the Official Agricultural Chamber and in May 1938, provincial union delegate in the province, a position in which he remained until May 1941.

[2] He was solicitor in Cortes by reason of his charges, between March 16, 1943 and April 14, 1958 and by designation of Francisco Franco between May 31, 1961 and November 11, 1967.
