An optical imaging lens assembly is provided. The optical imaging lens assembly includes, sequentially along an optical axis from an object side to an image side, a first lens, a second lens, a third lens, and a fourth lens. The first lens has a negative refractive power. The third lens has a positive refractive power. At least one of the second lens or the fourth lens has a positive refractive power. A center thickness CT2 of the second lens on the optical axis and a center thickness CT4 of the fourth lens on the optical axis satisfy: CT2/CT4
