Luis Emilio Recabarren Serrano (Spanish pronunciation: [lwis eˈmiljo rekaˈβaren]; 6 July 1876 – 19 December 1924) was a Chilean political figure.

After a trip to Antofagasta, Taltal and Tocopilla, Recabarren became aware of the extreme poverty and near-enslavement of the nitrate workers.

He initially focussed his political activities on the city of his birth, where he became director and editor of the newspaper El Trabajo (Work).

Heavily involved in the labour movement, organising workers both politically and industrially, as a consequence of which he was re-prosecuted by the government and had to escape to Argentina.

In that country he joined the Socialist Party of Argentina and in 1908 he travelled to Europe (Spain, France and Belgium), finally returning to Chile at the end of that year.

Previously, on 20 May that year, he had founded the El Despertar de los trabajadores (The awakening of the Workers) newspaper to promote his ideas.

During its existence (1912–1926) the newspaper was banned several times, but Recabarren continued preaching his socialist credo from any tribune he could get.

He refused to run for deputy in the 1924 elections and on December 19 of the same year he committed suicide in Santiago at the age of 48.
