A new Jaw-Closing Anti-Snoring System for controlling a user's snoring by supporting the user's jaw in a closed position while sleeping. The inventive device includes a strap having a first end and a second end, a securing means at the first and second end allowing the first end to removably secure to the second end, and an arcuate jaw support member formed to the shape of a jaw secured to the concentric portion of the strap and supporting the jaw of the user.
