Abstract: Embodiments of the present application relate to a lens assembly and a fingerprint identification module. The lens assembly includes a first lens, a second lens, and a third lens in sequence from an object side to an image side, and at least one of six surfaces of the three lenses is aspherical. The first lens is a negative optical power lens; the second lens is a positive optical power lens; and the third lens is a positive optical power lens. The lens assembly satisfies: 0.5<|Y?/(f*TTL)|<0.8, where Y? represents the maximum image height on a surface of the image side, f represents a focal length of the lens assembly, and TTL represents a distance from the object side to the image side. The lens assembly and the fingerprint identification module in the embodiments of the present application can effectively improve accuracy and identification speed of optical fingerprint identification.
