Rafael María de Labra y Cadrana (7 September 1840 – 16 April 1918) was a Spanish krausist educator, activist, lawyer, lecturer, Republican politician and author.

Born in Havana (both 7 September 1840 and 1841 have been reported as birth date),[1][2] son to Rafaela González Cadrana (a Cuban-Asturian) and Ramón María de Labra (a Liberal army officer from Asturias, defender of the 1812 Constitution who had been exiled during the Ominous Decade, destined to Cuba in 1836).

[11] He would earn again a seat as member of the Lower House in representation of Sabana Grande (Puerto Rico; 1872; 1874); Havana (1879) and Santa Clara (Cuba; 1885).

[16] Labra, who along his parliamentary history espoused autonomist stances vis-à-vis the Cuban question, remarked in 1898 that "he was not an advocate of the independence of our Antilles", always defending the compatibility of autonomy of the colonies and Spanish national integrity.

[7] According to the Count of Romanones, if Labra had reneged on his republican faith, he would have hold top offices in Spanish politics (of the Restoration), being reportedly asked several times to join the government.
