Santiago Rubio Rubio (died 1 February 1931) was a Chilean politician and member of the Radical Party. He served as Deputy for the 9th Departmental Circumscription (Maipo, Rancagua and Cachapoal) between 1926 and 1930.

Biography

He completed his studies at the Liceo de Rancagua.

In the 1926 parliamentary elections, he was elected Deputy for the 9th Departmental Circumscription of Maipo, Rancagua and Cachapoal for the 1926–1930 term. He served on the Committees of Budget and Objected Decrees, Industry and Commerce, and Public Works and Transportation, the latter two as substitute member.

One of his principal legislative concerns was the establishment of legal divorce in Chile. In May 1927, he introduced a bill composed of 19 articles, presenting comparative demographic data to support his proposal. The project was ultimately rejected.

He left office in 1930 and died on 1 February 1931 in Rancagua, Chile, after suffering paralysis while in Gualleco.
