A portable reading lamp includes a lower and an upper cover assembled together to enclose therein a printed circuit board (PCB), a plurality of light-emitting units, a laser-illuminating unit, a power supply unit, and switches for switching on and off the light-emitting units and the laser-illuminating unit. The assembled lower and upper covers define an inward curved front surface, from where the light-emitting units irradiate light onto a predetermined area to help in reading at a dark place without the need of a light-guiding plate, enabling a largely reduce size of the portable reading lamp. With the laser-illuminating unit, the portable reading lamp may serve as a laser pointer.
