Macron supporters gathered outside the Louvre museum in central Paris broke out in wild cheers and waved the French flag as the news came through.
39-year-old Macron is the youngest French President ever.
French far-right candidate Le Pen said she has called Macron to congratulate him on his victory and said the vote confirms her National Front party and its allies as the leader of France's opposition.

But she made a parting swipe at the winner's similarity to current president François Hollande.
"My dear compatriots from abroad and at home the French have chosen a new President of the Republic and they voted for continuity."
Minutes after the first results were released on Sunday, Le Pen said she would call for a new political force as legislative elections loom in June.
She hinted that her party may rename itself from the National Front, which has been dogged by allegations of racism and anti-Semitism since it was founded by her father.
If the polls are confirmed, Le Pen's showing would nonetheless be stronger than her National Front party has seen in its 45-year history.
The projections are based on vote counts in selected constituencies, then extrapolated nationwide.
But Le Pen's projected showing, unusually low turnout and the record number of blank ballots are an indication of the headwinds facing Macron, a former economy minister who started his own political movement only a year ago.
Sky's Michelle Clifford said more voters than ever may choose to abstain.
"They weren't satisfied with the two choices. Abstentions were predicted to be at a record high. It's looking at the moment that abstentions could hit a record level."
France's future in the European Union seems a little more certain, as the pro- European centrist candidate Macron is elected president.
Outgoing President Hollande said he's called Macron to warmly congratulate him and expressed his best wishes for success for France.
He said the victory shows most French people want to unite around the values of the Republic.
European Commission President Jean Claude Juncker said it shows French voters have chosen a European future.
