Anastasio de Gracia Villarrubia (18 September 1890 – 14 March 1981) was a Spanish bricklayer, trade union leader and socialist politician.

He attended the 13th congress of the UGT in 1918 as a delegate of the Bilbao reinforced concrete workers and the masons of Madrid.

[3] Gracia became a militant in the Partido Socialista Obrero Español (PSOE, Spanish Socialist Workers' Party).

[2] Gracia represented a wide range of sections of the National Building Federation at the UGT congresses.

He represented the AS of Madrid, Tembleque, Novelda and La Romana (Alicante) in the 12th PSOE congress in 1928.

[4] Gracia was president, José Díaz Alor vice-president, Pascual Tomás administrative secretary and Felipe Pretal treasurer.

The election represented a victory for those who felt that the union should participate in politics against those led by Julián Besteiro who thought the UGT and the PSOE should not get involved.

[5] In January 1936 Gracia resigned the UGT presidency due to objections to the way Caballero and his followers had been courting the Communist Party of Spain.

The two communist ministers demanded that Largo Caballero dissolve the anarchist Confederación Nacional del Trabajo (CNT) and the Trotskyist Partido Obrero de Unificación Marxista (POUM), and resigned when they were refused.

[9] On 14 May 1937 Negrín and Gracia met Largo Caballero to submit their resignations, which exacerbated the cabinet crisis.
