Érika Alejandra Olivera de la Fuente (born 4 January 1976 in Quinta Normal) is a female marathon runner from Chile and deputy for the Democrats party.

The following year she upgraded to a gold and a silver medal at the Pan American Junior Championships, before going on to complete a hat-trick of medals at the South American Junior Championships – she secured a 10,000 m and 3000 m double and also won the 1500 metres silver behind Bertha Sánchez.

[3][4] Olivera is a two-time winner of the South American Cross Country Championships, having beaten all comers in both the long and short races in 1999.

She enjoyed success on the track at continental level, completing a 10,000 metres/5000 metres silver medal double at both the 1997 and 2003 South American Championships in Athletics.

She gained controversy after she compared the campaign of former presidential candidate Alejandro Guillier to the government of Venezuelan president Nicolás Maduro.
