The vote was 50-48, falling largely along party lines, with most Republicans voting for Kavanaugh and only one Democrat Senator, Joe Manchin, also voting to confirm the controversial judge.
It was the end of a long ordeal that gripped the nation, with a Senate hearing that included "she said, he said" testimony by Ford, 51, and Kavanaugh, 53.
Ford claimed that Kavanaugh had attempted to rape her at a high school party when she was 15 and he was 17.
She testified that the incident took place in 1982, but couldn't remember the exact date—or who owned the home where she alleged he grinded against her.
None of the others she named as being at the party recalled it -- and they couldn't corroborate any of her claims.
Ford, the woman who first wrote a letter accusing Supreme Court nominee Kavanaugh of sexual assault, later went public with her story in a shocking Washington Post interview.
Ford claimed Kavanaugh viciously attacked her years ago and "I thought he might inadvertently kill me."
"He was trying to attack me and remove my clothing."
In a tearful statement before the Senate Committee, however, Kavanaugh cried and said, "I am innocent."
Kavanaugh also denied the sexual allegations against him by two other accusers.
He was even accused of being involved in gang rape by a third accuser, and vehemently denied those allegations as well.
But his first accuser, Ford, became a heroine to the #MeToo movement and most Democrats said they believed her.
Still, on Saturday afternoon, the Senate narrowly confirmed the conservative judge to sit on the Supreme Court.
The final vote was interrupted several times by protesters during the formal roll call.
"I do not consent, where's my representation," one hater yelled.
President Donald Trump, who nominated Kavanaugh after getting Judge Neil Gorsuch on the Supreme Court, wrote on Twitter after the confirmation, "I applaud and congratulate the U.S. Senate for confirming our GREAT NOMINEE, Judge Brett Kavanaugh, to the United States Supreme Court. Later today, I will sign his Commission of Appointment, and he will be officially sworn in. Very exciting!"
He becomes the 114th justice in United States history.
