Yasna Provoste Campillay (born 16 December 1969) is a Chilean teacher and Christian Democrat politician of Diaguita descent who served as a minister during the presidencies of Ricardo Lagos and Michelle Bachelet.

In 2008, following the fraudulent activities of civil servant Franka Grez,[5][6] Provoste faced questioning from parliamentarians of the then-center-right opposition, Alianza por Chile.

On April 14, the Chilean Senate, by a majority of 20 votes to 18, found her guilty in the "Subsidies case" (Spanish: Caso Subvenciones),[7] resulting in a loss of over US$600 million.

Meanwhile, Grez received a prison sentence of eleven years for embezzlement and diversion of funds to her relatives and close friends,[8] with the estimated amount being CLP 310 million.

During the Eduardo Frei Ruiz-Tagle administration Provoste was the director of the National Women's Service in the Atacama Region from 1996 to 1997 and governor of the Huasco Province from 1997 to 2001.

Thus, Provoste was accused by the opposition deputies Iván Moreira and José Antonio Kast,[4][14] both from the right-wing party Independent Democratic Union,[14] for not correcting these irregularities.

[32] After the activists' confrontation against Provoste, the political commentator Fernando Paulsen remarked that she and the official presidential candidate Gabriel Boric have been victims of false accusations;[33] in the case of Boric, the former communist candidate Daniel Jadue accused him of being responsible for allowing "political prisoners" in Chile by voting for the Anti-Barricade Law.

[37] Nevertheless, Maldonado openly criticized Provoste during the debate for announcing her candidacy late, making the Constituent Unity miss the legal primaries on 18 July.

[13] According to La Tercera, her centrist electorate was captured by Franco Parisi, who finished ahead of Provoste as well as the center-right candidate Sebastián Sichel.
