With the win, Nadal extended his head-to-head lead over Wawrinka to a stellar 16-3, and improves to a ideal 10-0 in French finals.
Two-thirds of Nadal's major titles have come at Roland Garros, where he has an astounding 79-2 record.
He said: "In 2005, I thought in 2017 I'd be fishing on my boat in Mallorca".
"I am really happy to win here".
"If I can do it, someone else can do it".
No other man or woman has won 10 championships at the same major in the Open era.
He said: "There has been a little while since I played a very good Wimbledon".
The win also earned him his 15th Grand Slam crown. After Wawrinka held for 1-1, Nadal saved the only break point he'd face for the next 90 minutes or so, then the onslaught began.
"He's playing the best he's ever played".
"But not only here. And I'm going to try to keep working hard to try to enjoy more lovely weeks". "So many reasons made that score today, but mainly because he was playing better". "That's why he's winning so much again". She is the lone other tennis player to reach double digits at the same major.
The Spaniard won 60% of his points in under four strokes, 72% of his first-serve points and a stunning 74% behind his second serve. "His level of play is unbelievable".
It was a steamy day in Paris - temperatures hovered around 30 degrees Celsius - a boost to Nadal's heavily spun forehand that can trouble players with one-handed backhands.
For the third time in his career, Nadal won every set at a grand slam.

Nadal's victory in Paris gave him a record 10th trophy at the clay-court tournament and ended his three-year drought without a Grand Slam title.
Nadal admits that if he suffers a new problem with his knees on the Wimbledon grass, where the lower bounce of the ball piles more pressure on the legs and joints, then his visit to London may again be short-lived. In his 39 matches, the Spaniard lost only 10 sets.
There were emotional scenes on Philippe Chatrier Court as Nadal's coach and uncle, Toni, was asked to take part in the trophy ceremony. We will see what happens during the rest of the year. So it has been, I think, a ideal Roland Garros for me.
"We are lucky in this life because we receive so much".
"For me, 10 is unbelievable", he said. "It's unbelievable. It's the last time as coach but I hope I can see more times him playing here". During the period from 2005 to 2014, he won nine French Open titles and in 2009 won the only Australian Open.
"When Rafael is good with his knees", Toni said, "he can play well on the grass". That's the second-fewest games lost at a Grand Slam best-of-five match. And I miss playing well at Wimbledon. "And back then, of course, I couldn't even think for a second that this would ever happen to me".
"You can't look too far ahead in the world of sport but who's going to stop him?"
His play at the French Open hasn't been, that's for sure.
"Wawrinka had a really tough semi (he needed five sets to beat Andy Murray)".
PARIS-Rafael Nadal will resume his bittersweet relationship with Wimbledon buoyed by his record-breaking French Open but wary of the traps which have ensnared him at the All England Club.
"I love grass, everybody knows".
"Four games he dropped at most - in any match and any set".
"You have to be humble and accept that you have to work to improve things".
Nadal celebrates victory after the match-winning point. "Winning one point is hard".
