Provided is a pneumatic tire for a motorcycle capable of improving grip performance while ensuring drainage performance, and also capable of attaining excellent wear resistance. The pneumatic tire for a motorcycle of the present invention includes a directional tread pattern having a plurality of different grooves formed on a tread surface, the grooves each converging forward in a rotation direction of the tire, in which: the plurality of different grooves are formed as three different oblique lug grooves (2a to 2c) extending, in a development plan view of the tread pattern, from a tread contact end of the tire to a tire equator line (e) as being curved to be deflected to the tire equator line side; the three different oblique lug grooves (2a to 2c) each have lengths α, &bgr;, γ, respectively, the lengths satisfying Expression (I) α≦̸&bgr;<γ, Expression (II) 1−γ/α<0.1; and the number n of the oblique lug grooves intersecting with a meridian (m) of the tire is defined to satisfy Expression (III) n≧4 (where the oblique lug grooves are assumed to be disposed within a range of 60% to 70% of the entire circumference of the tire).
