The invention discloses a portable cup. The portable cup comprises a cup body (1) and a cup handle (4). The cup body (1) is of an inverted circular truncated cone structure. Reinforcing rings (2) arearranged on the outer wall of the cup body (1) at intervals. A supporting rod (3) of a telescopic rod structure is further included, the supporting rod is conical, the cross section of the supportingrod (3) is of a trapezoidal structure, a dovetail groove (21) is formed in the outer side of each reinforcing ring (2), and therefore the supporting rod (3) can sequentially penetrate through the dovetail grooves (21). L-shaped connecting parts (41) are formed in the two end faces of the cup handle (4) respectively, grooves (31) are formed in the positions, close to the two ends, of the outer sidewall of the supporting rod (3), openings (311) are formed in the upper side walls of the grooves (31), and the connecting parts (41) can stretch into the grooves (31) and clamped into the openings (311). According to the portable cup, the dovetail grooves (21) matched with the shape of the supporting rod (3) are formed in the reinforcing rings (2), so that the supporting rod (3) and the reinforcing rings (2) are fixed, the cup handle (1) can be clamped into the supporting rod (3), and the whole cup body (1) can be supported.
