Surrounded by members of his family, Donald Trump greeted supporters at his campaign watch party in Florida.
The crowd was jubilant and chanted "USA" as he began to speak.
"Frankly, this was, I believe, this was the greatest political movement of all time. There's never been anything like this in the history in this country and maybe the earth," he began.
He then promised to "help heal our country" by, for example, "fixing our borders."
"I would like to thank the American people for being elected your 47th president," he added, vowing to fight for "every citizen."
"I will not rest until we have delivered the strong, safe, and prosperous America that our children deserve."
Trump then said he won the popular vote, which cannot yet be determined with certainty.
He thanked his family and praised vice presidential nominee JD Vance, before calling media organizations like CNN "the enemy camp."

Trump invited his vice presidential candidate to address the crowd.
Vance said, "We just witnessed the greatest political comeback in American history."
Trump then joked "I made a good choice," about Vance. He then added "I took a like heat in the beginning" for choosing Vance, but now he knew that the former venture capitalist had the right "brain" for the job.
Donald Trump claims victory
Donald Trump has claimed victory after several US media outlets projected him to win the 2024 presidential election. Other media groups projected him three votes shy of victory at the time of his speech.
Speaking in Palm Beach, Trump said he achieved a victory "the US has never seen."
"America has given us an unprecedented and powerful mandate," he told supporters.
The Republican candidate has already won the key battleground states of Pennsylvania, Georgia and North Carolina.
He said he is also on track to win the swing states of Arizona, Michigan and Nevada.
Meanwhile, the Republicans have also won a majority in the Senate.
Vice President Kamala Harris won a number of blue states but was not in a strong position in the remaining battleground states. She has not yet spoken on the results.
