And whether you love or loathe him, it's a fact that the Republican will set a range of records as soon as he occupies the Oval Office.
From his age to his bank balance, via his notable lack of pets - here are just some of "The Donald's" historic "firsts".
Oldest incoming president
Donald Trump celebrated his 70th birthday on 14 June, which makes him the oldest man in US history to assume the presidency. The previous record-holder, Ronald Reagan, was 69 when he took office in 1981.
Perhaps keen to allay fears about his senior status, the business mogul had his doctor prepare a gushing letter pledging that he would be "the healthiest individual ever elected to the presidency".
The first billionaire president
Mr Trump is the first billionaire president. Exact estimates of his personal wealth vary, with Forbes putting it at $3.7bn (£3bn) and the man himself claiming in a statement that it's "in excess of TEN BILLION DOLLARS".
Many of America's past presidents have also been extremely wealthy, of course. Recent estimates say George Washington's estate would be worth half a billion in today's dollars.
The richest cabinet
When Mr Trump began unveiling his cabinet picks, the number with fat wallets quickly drew the scorn of Democrats.
"Donald Trump's administration: of, by and for the millionaires and billionaires," tweeted Vermont Senator and Democrat presidential contender Bernie Sanders.
For better or worse, this will be the wealthiest administration in modern American history.
Least experienced politically
Mr Trump's triumph is also significant because, until now, no-one has been elected president in more than 60 years without experience as a state governor or in Congress.
But as Mr Trump tells it, his lack of links to the Washington establishment is an asset, not a flaw - and more than made up for by his experience as a deal-maker.
Fewest White House pets
So much fuss has been made of what Donald Trump owns that you might have missed one glaring absence - a pet.
It looks likely that he'll be the first US President in over a century not to have an animal pal in the White House
The First Lady's firsts
Former model Melania Trump is as trailblazing as her husband. She will be the first presidential spouse from Slovenia, and the first non-native English speaker.
As Mr Trump has been married twice before, Melania will also be the first third wife to reside in the White House.
Melania speaks Slovenian, English, French, German, and Serbian, and may be the most competent linguist to hold the role of FLOTUS.
