A lamp for a vehicle allows a pedestrian to identify a state of the vehicle by displaying an emblem, logo, or driving status of the vehicle. The lamp for the vehicle includes a substrate; a light source unit including a plurality of light sources disposed on the substrate to generate light; a lens unit including a plurality of optical lenses through which the light is transmitted; and an imaging sheet on which the light transmitted through the plurality of optical lenses is projected to form a lighting image. In particular, each of the plurality of optical lenses is formed in a right triangle shape.
