Den Bristol Type 192 Belvedere er et britisk tomotors tandemrotor militærhelikopter bygget av Bristol Aeroplane Company. Den ble designet av Raoul Hafner for en rekke transportroller, inkludert troppetransport, forsyningsfall og evakuering av havari. Det ble operert av Royal Air Force (RAF) fra 1961 til 1969. Belvedere var Storbritannias eneste tandemrotorhelikopter som kom i produksjon, og et av de få som ikke ble bygget av Piasecki eller Boeing.
