A lamp for a vehicle that radiates a beam pattern to a vehicle front side is provided. The lamp for a vehicle includes at least one light source and a lens configured to radiate a low beam to a front side of the vehicle through refraction of light emitted from the at least one light source. The lens includes a light incident portion that light emitted from the light source is incident and a light exit portion from that refracts and exits the light. The light exit portion includes a plurality of facets formed to have independent curvatures to refract the light from the light source and to form a beam pattern of the low beam. The portions of the plurality of facets are inclined with respect to a virtual vertical line having at least portions of boundary lines formed between the inclined facets and the neighboring facets.
