Bell R-12 (Model 48), kasneje Bell H-12 je bil enomotorni batnognani večnamenski helikopter, ki ga je razvil ameriški Bell Helicopter v 1940ih. Sprva so zgradili dva prototipa z oznako "XR-12", ki sta imela 5 sedežev in jih je poganjal 540 konjski zvezdasti motor Pratt & Whitney R-1340-AN-1. Kasneje so zgradili večjega "XR-12B", ki je imel 10 sedežev in ga je poganjal 600 konjski zvezdasti motor Pratt & Whitney R-1340-55. Oba helikopterja so kasneje po maloserijski proizvodnji preklicali.
