The UFC president and MMA promoter Dana White said the bout would take place at the T-Mobile Arena and it would be a boxing match at 154-pounds with 10 ounce gloves.
"We have been in negotiations for a while," White told ESPN. "The negotiations went smooth. Floyd Mayweather surrounds himself with smart people and we got the deal done."
Neither Mayweather or McGregor have competed this year. Mayweather retired from pro boxing in 2015 after defeating Andre Berto, while McGregor (21-3) defeated Eddie Alvarez in November 2016.
White said the key to finalising the fight was luring Mayweather out of his 23-month retirement.
"Everybody is happy with this deal," White said. "Nobody is bummed out."
The boxing format heavily favours the undefeated Mayweather (49-0, 26 KOs) who many consider to be the best pound-for-pound fighter in the world.
McGregor, a 28-year-old Irishman, will be entering unknown territory as he has not stepped in a boxing ring since he was a teenager.
