An object is to provide a straddled vehicle including a single-cylinder four-stroke engine unit including a horizontal cylinder member, in which the purification performance of a catalyst purifying exhaust gas is improved while the structure of an exhauster is simplified. It is assumed that the straddled vehicle 1 is viewed in an up-down direction. The upstream end 35a of a silencer 35 is provided one of leftward and rightward of the downstream end 31 b of a cylinder exhaust passage member 31. A main catalyst 39 is arranged so that the center of the downstream end is on the one of the leftward and rightward of the center of the upstream end. The main catalyst 39 is provided to at least partially overlap a quadrangle S10 which is formed of a side S11 which passes the downstream end 31 b of the cylinder exhaust passage member 31 and is parallel to a cylinder axis Cy1, a side S12 which passes the downstream end 31b of the cylinder exhaust passage member 31 is parallel to a crankshaft axis Cr1, a side S13 which passes the upstream end 35a of the silencer 35 and is parallel to the cylinder axis Cy1, and a side S14 which passes the upstream end 35a of the silencer 35 is parallel to the central axis of the crankshaft axis Cr1.
