The invention provides a dashboard tubular beam mounting structure and an automobile. The dashboard tubular beam mounting structure comprises an A-pillar interior panel and a tubular beam mounting plate which is positioned on one side of the A-pillar interior panel; tubular beam mounting holes, which run through the tubular beam mounting plate and the A-pillar interior panel, are formed in the tubular beam mounting plate and the A-pillar interior panel; the dashboard tubular beam mounting structure further comprises a longitudinal beam which is positioned on the other side of the A-pillar interior panel relative to the tubular beam mounting plate; and first chambers, which are placed on the two sides of the A-pillar interior panel, are respectively enclosed between the tubular beam mounting plate and the A-pillar interior panel and between the A-pillar interior panel and the longitudinal beam. According to the dashboard tubular beam mounting structure, as the first chambers are respectively enclosed between the tubular beam mounting plate and the A-pillar interior panel and between the A-pillar interior panel and the longitudinal beam, the structural strength of the mounting position of a dashboard tubular beam can be enhanced by using high strength characteristics of the chamber structures so as to enhance the modality of the dashboard tubular beam; and meanwhile, the structural strengths of mounting points of a door hinge and a door check in the A-pillar area of an automobile door can also be enhanced; and the quality of the whole automobile can be improved.
