Nadal, 31, triumphed 6-2, 6-3, 6-1 to become the first man in history to win the same major 10 times.
His collection of Slams now stands just three behind great rival Roger Federer, a staggering statistic coming just a year after he quit Roland Garros with a wrist injury.
Playing in his 22nd Grand Slam final, Nadal triumphed in Paris without dropping a set for a third time.
He also lost just 35 games in total and only six in the final, his most comprehensive victory since allowing Roger Federer four games in the 2008 final.
"It's really incredible. To win La Decima is very, very special," said Nadal.
"I am very emotional. The feeling I have is impossible to describe.
"It's difficult to compare with other tournaments but the nerves and adrenaline I feel, it's like no other place."
Nadal was joined on the presentation by his uncle Toni, his coach since boyhood, who is stepping down at the end of the year.
"Without my uncle I would not have won 10 trophies," said Nadal who will rise to two in the world rankings on Monday.
"For me to be here for many years is difficult to describe. I come back and see people I have a good relationship with and it's very special.
