A portable terminal with a hinge apparatus is provided. The portable terminal includes a hinge apparatus which pivotally couples a pair of housings together. The hinge apparatus provides a first hinge axis and a second hinge axis which are perpendicular to each other. The hinge apparatus includes a first hinge shaft coupled to the first housing along the first hinge axis, a second hinge shaft coupled to the second hinge housing along the second hinge axis and rotating about the first hinge axis and the second hinge axis, a stopper slot formed on an outer circumferential surface of the first hinge shaft along the first hinge axis, a stopper groove formed on the second hinge shaft along a circumference thereof and encompassing a part of the outer circumferential surface of the first hinge shaft, and a stopper rib formed within the stopper groove and selectively engaging with the stopper slot. Thus, when one of the housings is rotated about one of the hinge axes, the housing is restricted from rotating about the other hinge axis.
