Earlier Twitter said the President's account was "inadvertently deactivated due to human error by a Twitter employee".
"The account was down for 11 minutes, and has since been restored," it tweeted. "We are continuing to investigate and are taking steps to prevent this from happening again."
The disappearance of Mr Trump's account caused a frenzy online.
About 10am AEDT those who went on to the US President's page got an error message saying: "Sorry, that page doesn't exist".
But just a few minutes later it reappeared. Mr Trump's Twitter did not acknowledge the temporary disappearance and later posted a tweet about tax cuts.
About half an hour earlier, Mr Trump had tweeted a video about his nomination of Jerome Powell to be the next chairman of the Federal Reserve.
He had also posted a number of tweets about the move of Broadcom headquarters back to the US and the cancellation of the diversity visa lottery program following the New York truck rampage.
Overnight Mr Trump drew criticism for his comments that the alleged driver should be sent to Guantánamo Bay detention camp and get the death penalty.
The disappearance of Mr Trump's account sparked speculation about whether it was deleted by Twitter or if the President did it himself. Some simply rejoiced in the President's brief absence from social media.
