Bell 222 je dvomotorni lahki helikopter ameriškega podjetja Bell Helicopter. Načrtovanje lahkega dvomotornega Bellovega helikopterja se je začelo v poznih 1960ih. Bell 222 je imel veliko novosti: dvojne hidravlične in električne sisteme, sponsone za uvlačljiva kolesa in sistem Noda Matic za zmanjševanje vibracij. Na podlagi 222 so zgradili močnejšega Bella 230 in kasneje še večjega Bell 430.
Helikopter je certificiran za enopilotno IFR letenje.
