Abstract: A structure of a hybrid front pillar of a vehicle includes a front pillar lower portion which is disposed at a front side of a front door unit of a vehicle, and has a lower end coupled to a side connecting member; and a front pillar upper portion which is disposed at an upper side of the front pillar lower portion, and coupled to the front pillar lower portion, in which a recessed portion is formed at one side of the side connecting member such that the lower end of the front pillar lower portion is inserted into the recessed portion, and a mounting portion is formed at a lower end of the front pillar upper portion such that an upper end of the front pillar lower portion is inserted into the mounting portion, thereby significantly reducing a weight of the vehicle body, enhancing rigidity of the front pillar, and omitting reinforcing components.
