A nasal dilator (10) is disclosed which is adapted to be inserted in the nostril of the human nose to prevent the tissues of the ostium internum of the nose from drawing in during breathing. The device includes generally elongated top and bottom rings (11, 12) which are spaced apart and connected together by a rear strut (13) and a front strut (14). The front strut (14) is longer than the rear strut (13) and includes a bend (15) therein formed at a position close to the front end of the bottom ring (12). One elongated side (17) of the top ring (11) may be concaved to better fit the septum at the ostium internum, and an elongated side (18) of the bottom ring (12) may also be concaved for maximum wearer comfort. When emplaced in the nose, the top ring (11) fits comfortably in the ostium (31) within the nostril to prevent the tissues therein from being drawn in during inhalation and to reduce extra flow resistance during exhalation, and the bottom ring (12) fits above the entrance to the nostril and serves to stabilize the position of the top ring within the nostril.
