The North East 250 circuit includes Deeside, the Cock Bridge-Tomintoul road and the coast from Buckie to near Aberdeen.
It has been developed by businessman Guy Macpherson-Grant in an effort to attract more tourists to the region.
He said: "I am excited by the potential of the North East 250 to bring more visitors to our area and experience, what I believe, is the very best that Scotland has to offer.
"We need businesses along the route to really get behind it and help make it the success I know it can be.”
Backers include Chivas Brothers, Ballindalloch Castle and Gardens, Turcan Connell, Walkers, Aberdeen Airport, Speyside Gardens and the Station Hotel in Rothes.
Moray Speyside Tourism operations manager Laurie Piper said: “I am confident the North East 250 will contribute to the continued growth and development of the tourism industry."
VisitScotland regional director Jo Robinson said: “This exciting new route is a welcome asset to the north east and will, we would hope, simulate the success of other similar routes around Scotland.
“This area has arguably the best scenery, landscapes and views in Scotland and we would anticipate the introduction of such a route will bring economic benefit to the area and its tourism businesses through increased visitors."
The North Coast 500 has been joined by the South West Coastal Route 300 in Dumfries and Galloway and Ayrshire, which takes in Kirkcudbright, Glenluce, Portpatrick, Sanquhar and Girvan.
