The invention relates to an LED (Light Emitting Diode) headlamp for a motorcycle. The headlamp comprises a lamp shell, a lampshade, a daytime running light assembly obliquely arranged in the shell and a dipped headlight assembly and a headlight on full beam assembly below the daytime running light assembly, wherein the daytime running light assembly comprises a strip base plate, a plurality of daytime running light reflectors arranged on the strip base plate, and LED daytime running light beads arranged in the daytime running light reflectors; the dipped headlight assembly comprises a dipped headlight reflector, an LED dipped headlight bead arranged in the dipped headlight reflector, a dipped headlight lens in front of the dipped headlight reflector and a shield arranged between the dipped headlight lens and the dipped headlight reflector; and the headlight on full beam assembly comprises a reflector of the headlight on full beam and an LED headlight bead on full beam arranged in the reflector of the headlight on full beam. The LED is used as a light source, so that the headlamp for the motorcycle has the advantages of energy saving, environmental friendliness, long service life, small heating amount, high brightness and the like; and the dipped headlight, the headlight on full beam and the daytime running light are arranged in a same shell, and have relatively independent light distribution systems, so that the headlamp is simple and compact in structure and good in light distribution effect.
