Sebastián Silva Irarrázabal (born 9 April 1979; Santiago) is a Chilean director, actor, screenwriter, painter and musician.

The second of seven brothers, Sebastián Silva was born in Santiago, Chile on 9 April 1979. After graduating from the Catholic Colegio del Verbo Divino school in Santiago, he spent a year studying filmmaking at the Escuela de Cine de Chile (“Film School of Chile” in Spanish) before leaving to study animation in Montreal, Canada. Here, he mounted the first gallery exhibition of his illustrations and started the band CHC, which went on to record three albums. Silva's second illustration show brought him in contact with Hollywood but a “frustrating period” in Los Angeles, spent pitching to Steven Spielberg and others, brought no tangible results. Leaving Hollywood, Silva started two more bands, Yaia and Los Mono, the latter of which was signed by British record label Sonic360.
