Luis Alejandro Silva Irarrázaval (born 24 March 1978) is a Chilean conservative politician who served in the Constitutional Council.

[8] Silva was born and raised in a conservative family close to the political ideas of Jaime Guzmán, a lawyer and ideologue of Pinochet regime who drafted the Constitution of Chile in 1980.

[9] He hinted that his relationship with Sebastian was distant, but that he felt respect for him and that it made him feel ashamed to be considered a 'danger'.

From 2013 to 2014, he was part of the James Madison Program at Princeton University, where he was the William E. Simon Visiting Fellow in Religion and Public Life.

[12] In 2018, Silva met José Antonio Kast in the conservative think-tank, Jaime Guzmán Foundation (FJG).
