Plurinational Unity of the Lefts (Unidad Plurinacional de las Izquierdas) was a left-wing political coalition in Ecuador, created in 2011 and Dissolved in 2014.
In 2009, Pachakutik and the Democratic People's Movement (MPD) broke with the ruling PAIS Alliance over disagreements on water law and teacher evaluations.
In the National Assembly, a new caucus formed called the Plurinational, Progressive, and Leftist Democratic Assembly, composed of Pachakutik and MPD assemblymen and assemblywomen.
Plurinational Unity of the Lefts participated in the referendum and popular consultation of 2011, advising a "no" vote on questions 1-9, and "yes" on 10.
Beginning on 8 March 2012, Plurinational Unity of the Lefts participated in a series of peaceful protests, commonly called the 8-M Movement, by indigenous groups, left-wing opponents of the government, environmental groups, LGBT groups, and students, which culminated in the arrival of more than 30,000 people in the streets of Ecuador.
