The 18-year-old, who can operate either as a left-back or left-winger, has signed a contract which will keep him at Stamford Bridge until the summer of 2018.
Cuevas came through the youth ranks at O'Higgins to make a handful of senior appearances, before shining with Chile at this summer's Fifa Under-20 World Cup, playing in four of their five matches.
The Blues moved to tie up the deal after the youngster impressed on trial at the club in November.
Cuevas becomes Chelsea's fourth signing of the summer, following the arrivals of Andre Schurrle from Leverkusen, Marco van Ginkel from Vitesse and free agent Mark Schwarzer.
