Patriotic Union (Spanish: Unión Patriótica, UPA) was a far-left Chilean political party.

It was founded in September 2015 and is led by Eduardo Artés, general secretary of the Chilean Communist Party (Proletarian Action).

The party obtained 0.32% of the total votes but no candidates were elected to any council.

[9][10] For the 2017 elections, the party proclaimed Artés as its presidential candidate, where he finished in seventh place in the first round.

It was reregistered in 2019, but dissolved again in February 2022 after failing to obtain at least 5% of the vote in the 2021 parliamentary elections.
