Las Vegas mass shooter Stephen Paddock may have had another target in mind.

Last weekend, he tried to rent a room overlooking a music festival a few miles away from the scene of his carnage Sunday, a law-enforcement source told The Post.

But Paddock couldn’t get a room that looked out onto the Life is Beautiful Festival, headlined by Chance the Rapper and Lorde and held in Sin City Sept. 22-24, the source said.

That festival was held several miles north of the Route 91 music festival that the cowardly Paddock sprayed with bullets from a 32nd-floor suite in the Mandalay Bay casino on Sunday.
