Ramón Barros Luco (Latin American Spanish: [raˈmom ˈbaros ˈluko]; June 9, 1835 – September 20, 1919) was President of Chile between 1910 and 1915.

In addition, he lent his support to the uprising of the National Army, whose movements he oversaw, (alongside Waldo Silva, vice-president of the Senate), until they took their place in the government in Iquique.

The revolution having succeeded, he resumed his functions as a parliamentarian, performing as a minister on several occasions, whenever the situation called for, "someone who posed no threat to anybody".

He applied this maxim to his administration, which would be consumed by the machinations of the parliament at large, the propensity of which was to delay or hinder the government under any pretense, including the most trivial claim of a minor deputy.

Meanwhile, the corruption amongst the political parties had reached alarming levels, in answer to which laws against fraud were approved in 1914 and 1915, in addition to a reform of the municipal system, which managed to eliminate the falsification of results, allowing for greater transparency.

This pact, signed between the so-called "ABC Powers" (Argentina, Brazil and Chile), was a means to combat the influence of the United States in the region, as well as to establish an equilibrium and channels of communication between the three signatories.
