Tour director Christian Prudhomme praised the "outstanding beauty" and varied terrain of Yorkshire.
He said: "Since the resounding success of the Grand Depart in London in 2007, we were very keen to return to the United Kingdom.
"Bradley Wiggins' historical victory last July and the enormous crowds that followed the cycling events in the streets of London during the Olympic Games encouraged us to go back earlier than we had initially planned.
"Yorkshire is a region of outstanding beauty, with breathtaking landscapes whose terrains offer both sprinters and attackers the opportunity to express themselves.

British Cycling president Brian Cookson said: "Like every other cycling fan, I am thrilled the world's biggest bike race is coming back to this country.
"The huge numbers who turned out to support the 2007 Grand Depart and the London 2012 road races show the passion we have for cycling.
"I'm sure Yorkshire will give the 2014 Tour de France a welcome which will stand out in the race's rich history."
The Mayor of London Boris Johnson said: "I am thrilled that the Tour de France will return to the UK and no location could be better than London for what will no doubt be an exhilarating climax to the British section of the race.
"This year we proved our expertise not just in hosting world class sporting events, but in winning them too, and I am sure Bradley Wiggins and several of his compatriots will be hugely excited at the prospect of the Tour returning to their home streets."
