Sebastián Iglesias Sichel Ramírez (born 30 July 1977) is a Chilean lawyer, professor, mayor elect of Ñuñoa, ex minister of State and politician who served as president of the Banco del Estado de Chile (BancoEstado) from June 2020 until December 2020.

[9] He then met his biological father for the first time at age 30 and changed his paternal surname back to Sichel, but retained Iglesias as his middle name out of affection.

In a controversial move, he resigned from the Christian Democratic Party in 2015, distancing himself from emblematic figures such as Claudio Orrego, whose presidential candidacy Sichel worked for in 2013.

Sichel argued that, in the immigration debate, Chile Vamos had shown "irresponsibility," creating "an anti-immigration climate that is exactly the opposite of what the country needs today.

[5] He received 49% of the vote, beating three other candidates including Joaquín Lavín, who previously ran in the 1999 and 2005 presidential elections and was considered a frontrunner in the primary.

[32] In the midst of the COVID-19 pandemic in Chile and the high level of unemployment in the country, on 18 May 2020, President Sebastián Piñera announced from inside La Moneda the delivery of a family basket in aid for the entire middle class.

Sichel, in his position as Minister of Social Development and Family, had to publicly correct the president's announcement, maintaining that the "percentage of the population benefited" will only have a scope for "70% of the most vulnerable 40%".

Former minister Cristián Monckeberg was then assigned to the Ministry of Social Development and Family, replacing Sichel, who was appointed as president of BancoEstado.
