Kavanaugh, 53, of Maryland, currently a judge in the US Court of Appeals for the District of Columbia Circuit, has "impeccable credentials and one of the finest legal mind of our times", Trump announced during his prime time address to the nation from the White House.
Trump picked Justice Kavanaugh from his original list of 25 judges, from which he had said he would nominate for any vacancy in the Supreme Court.
The nomination of Judge Kavanaugh comes after a selection process marked by a historic degree of transparency, including the President's public disclosure of a list of 25 highly qualified potential nominees to the Supreme Court.
"I am deeply honoured to fill his seat in the Supreme Court," said Judge Kavanaugh.
Before becoming a judge, he served in the George W Bush administration, first as an associate counsel and then senior associate counsel, and subsequently as assistant to the president and the staff secretary.
He has earned a reputation as a brilliant jurist with impeccable legal credentials, and he is universally respected for his intellect, as well as his ability to persuade and build consensus.
