5★STAR Grand Prix 2026 in Utsunomiya was a professional wrestling event promoted by World Wonder Ring Stardom, held on August 2, 2026 at Light Cube Utsunomiya in Utsunomiya, Tochigi, Japan. It served as the eighth show for the company's annual round-robin singles tournament, and mostly featured Blue Stars block matches, though one Red Stars match featuring Rina was included so all of the "Three Sisters" could be a part of this home-prefecture event.
