The world No 1’s 17th Major title came with a 6-4, 6-3, 6-2 win over Dominic Thiem on Court Philippe Chatrier, where he has never lost a final.
That takes his overall record to 86 wins in 88 outings, only ever losing to Robin Soderling and Novak Djokovic having monopolised Paris’ clay courts since his first crown in 2005.
Bjorn Borg is the next most successful Open Era player in the French capital with six successes - Nadal having managed five consecutive wins alone between 2010 and 2014.
But the Spaniard does not believe he employs any particularly outlandish tactics at Roland Garros and attempted to downplay his achievements at the French Open.

Rafael Nadal is a formidable, almost unstoppable, force on French clay
In most of the games I went out to play here in Paris, I went out onto the court thinking that I could win or I could lose and this is the truth.
"I would say that I am an ordinary person who has done something difficult or very difficult," he told Marca when asked about his stunning feat.
"This is the reality; things happen from day-to-day. In most of the games I went out to play here in Paris, I went out onto the court thinking that I could win or I could lose and this is the truth.
"I have won 86 of the 88 games I have played, and maybe in 75 of those, I have gone out thinking that I could win or I could lose. I think this is part of the basis of my success."
Rafael Nadal was emotional after creating further French Open history with an 11th triumph
The 32-year-old is behind only long-time rival Roger Federer, with 20, in the all-time list of Grand Slam champions.
Having claimed all of the last six between them, Nadal and Federer will be among the favourites to be victorious in the Tour’s next Slam - Wimbledon - next month.
Nadal has won just two SW17 titles, with Federer the most successful player in history at the All England Club, with the most recent coming way back in 2010.
