Hernán Barcos (Spanish pronunciation: [eɾˈnam ˈbaɾkos];[a] born 11 April 1984) is an Argentine professional footballer who plays as a forward for Alianza Lima.

He then went on to play on loan for Club Guaraní (Paraguay), Olmedo (Ecuador), Red Star Belgrade (Serbia), and Huracán (Argentina).

On 7 October 2007, Barcos scored his first Serbian SuperLiga goals by netting twice in the late minutes versus Banat Zrenjanin, helping Red Star to get three points.

He scored 14 goals in 14 league games with Shenzhen and won Chinese Football Association Golden Boot award in the end of the season.

He failed to score a single goal in the finals against Universidad de Chile, and though only ended up as runner up in the competition, he and the rest of LDU Quito received support and appraisal from the club's fans.

Even though LDU Quito was suffering from debt, they honored Barcos' wishes to play for Palmeiras, and on 17 January 2012, he signed for the Brazilian team.

[3] Barcos promised to achieve a total number of 27 goals in his first season with Palmeiras, thus showing a countdown of how many are left to go on his football shoes.

On 27 February 2012, football specialist Lédio Carmona compared Barcos to a lobster, playing with coach Luiz Felipe Scolari who had said he wanted shrimp, meaning the quality of Palmeiras' signings for the new season.

His debut came on 14 February, also scoring from the penalty spot, in a 2–1 home loss in a group-stage match up against Chilean Primera División side Huachipato.

On 16 February 2012, after a comparison with Brazilian singer Zé Ramalho made by Léo Bianchi, journalist of Rede Globo, Barcos cursed the reporter, calling him "boludo", a popular scold in Argentina.
