The purpose of the present invention is to provide an orthodontic bracket on which a ligature member can be easily hooked, and is capable of preventing the ligature member from becoming detached and of reducing friction during movement of teeth. An orthodontic bracket (11) includes a plate-like base portion (12) disposed such that a back surface (15a) thereof opposes a tooth surface, a pair of projecting portions (21a, 21b) projecting in the thickness direction from a front surface (15b) side of the base portion (12) with a space between the projecting portions (21a, 21b) such that they form a groove-like slot (22) in which an arch wire (44) is accommodated, and a pair of wing portions (31a, 31b) projecting from the pair of projecting portions in outward directions. Hook grooves (36a, 36b) for inserting a ring (45) therein are formed between the back surfaces of the pair of wing portions and the upper surface of the base portion. Hooking portions (28a, 28b) in deep portions of the hook grooves are provided at positions separated upward from the arch wire that is accommodated in the slot.
