Chile won the Copa America for the first time in the tournament's 99-year history when they beat Argentina 4-1 on penalties after 90 minutes and extra-time failed to produce a goal.
Alexis Sanchez netted the clinching goal from the spot after Gonzalo Higuain and Ever Banega had missed for Argentina.
The nail-biting finish came after a tense goalless draw in which neither side dominated and clear-cut chances were few and far between.
Chile had beaten Argentina just once in 38 competitive matches before the final and celebrated the triumph in front of an ecstatic home crowd at the National Stadium.
Among the thousands of Chilean fans were the famous 33 miners, who were trapped underground for 69 days, attended the final "to witness another miracle" - the victory of their national team.

"This is something so nice for all the Chilean people," midfielder Arturo Vidal told reporters.
"We Chileans needed a triumph, something like this Cup, today we took an incredible step, we're [South] America's best."
Sanchez dinked his penalty into the middle of the goal with Chile's fourth kick to guarantee the shootout win.
Lionel Messi scored with Argentina's first penalty then watched Higuain shoot his over and Banega have his saved by Chile captain Claudio Bravo.
It was Higuain who had come closest to breaking the stalemate for Argentina in the last minute of regulation time.
Messi sent Ezequiel Lavezzi through on the left and he crossed to Higuain at the far post but the striker put the ball in the side netting.
Sanchez had one great chance to steal the game for Chile in extra time but shot wide with just goalkeeper Sergio Romero to beat.
