She was born at 7:03 p.m. at Lenox Hill Hospital in New York City, ABC News has learned.
Her parents, former President Bill Clinton and former Secretary of State Hillary Clinton, said Saturday in a statement that they are "blessed, grateful, and so happy to be the grandparents of a beautiful girl."
"We are thrilled to be with our daughter and her husband as they welcome their daughter into the world," the statement continued. "Chelsea is well and glowing. Marc is bursting with pride. Charlotte's life is off to a good start."
The former first daughter announced that she was pregnant in mid-April.
President Obama even got in on the due-date jockeying, joking while at the Clinton family's foundation event in New York that she might have to commandeer his motorcade.
"I was just discussing with President Clinton that if Chelsea begins delivery while I'm speaking, she has my motorcade and will be able to navigate traffic," Obama said with a smirk.
The former first daughter didn't let her impending due date slow her down as she appeared at an event for her family's foundation this past week.
Clinton, 34, and her husband Marc Mezvinsky reportedly chose not to learn the sex of their baby before the birth.
She resigned from her role at NBC News on Aug. 29. Clinton and her husband "look forward to welcoming our first child," she wrote in a note she shared on social media at the time.
Her parents have regularly mentioned their joy at earning a new title -- grandparents. The former president spoke of his high hopes for the newest member of the family while speaking with ABC News' George Stephanopoulos at the 2014 Clinton Global Initiative annual meeting.
"I want them to get up every day and look at the world with wonder and reverence. I want them to respect everyone they meet, whatever their background. I want them to be aware of all the people that make their world and not just the people that they are introduced to," Clinton said.
"I want them to really love being alive. It's my first and whatever other grandchildren I have -- that's what I want. And when they grow up, I want them to believe they have certain obligations to people who don't have all the opportunities they'll have and to the larger society," he said.
