Electoral authorities said the 68-year-old conservative, who previously led the South American nation from 2010-2014, had 55 percent of the vote, with 98 percent of ballots counted, presstv.com reported.
His leftist rival Alejandro Guillier, a 64-year-old TV presenter turned senator who ran as an independent backed by outgoing center-left President Michelle Bachelet, conceded after receiving 45 percent.
“We have suffered a tough defeat,” Guillier said. He called for the opposition to “defend” reforms started under Bachelet.

Pinera will lead the country — the world’s top copper producer — for four years starting in March 2018.
He will once again take over from Bachelet, who was barred by the constitution from running for re-election.
Bachelet and Pinera have tag-teamed the presidency since Bachelet first took office in 2006. Since then, they have alternated in power, switching Chile’s politics between center-left and center-right each time.
Pinera supporters were gathered outside his election headquarters in anticipation of his victory speech.

The outcome of the runoff had been far from certain after Pinera scored a much lower than expected 37 percent in the first round of the election held November 19.
Voting had taken place under a somber cloud Sunday, following the deaths of 11 people and the disappearance of 15 others in a mudslide in a southern town.
The picturesque village of Villa Santa Lucia was unable to vote in the runoff.
Pinera and Guillier also promised to expand free university tuition brought in under Bachelet — a measure with historical resonance in Chile because paid tuition was introduced under Pinochet's 1973-1990 rule.
For Pinera, the vow was a U-turn, contradicting an earlier statement he had made that free things mean less commitment.
