商务喷射机（business jet）为一种用于私人、企业人员和政府要员运输的喷射客机。在两岸有不同的名称，又称公务喷射机或行政专机。

和航空公司的客机出售机票给个别乘客不同，商务喷射机若为私人所有，通常称为私人喷射机（private jet）；若为企业所有，则称为公司喷射机（corporate jet）。除了上述的营运形式外，也有专门从事商务喷射机出租服务的专门业者；向这些公司租用商务喷射机，则又可称为包机（charter）。

A business jet, private jet, or bizjet, or simply B.J., is a jet aircraft designed for transporting small groups of people. Business jets may be adapted for other roles, such as the evacuation of casualties or express parcel deliveries, and some are used by public bodies, government officials or the armed forces.
