A wide-angle lens assembly includes a first lens, a second lens, a third lens, a fourth lens, and a fifth lens, all of which are arranged in order from an object side to an image side along an optical axis. The first lens is a meniscus lens with negative refractive power. The second lens is a meniscus lens with positive refractive power. The third lens is with positive refractive power and comprises a convex surface facing an object side. The fourth lens is with positive refractive power. The fifth lens is with negative refractive power. The wide-angle lens assembly satisfies: 3
