The invention discloses a lens array, a vehicle lamp lens group, and a vehicle lamp assembly. A lens array is disposed on a substrate and includes a plurality of converging lenses. The converging lenses are configured to project light beams and are arranged along a first direction. Two of the light beams respectively converged by adjacent two of the converging lenses at least partially overlap with each other by geometry of the adjacent two converging lenses, a distance between the adjacent two converging lenses, or a combination thereof, thereby improving the uniformity of the light beams projected by the lens array.
