An optical imaging lens assembly is provided, which includes, a first lens having a negative refractive power; a second lens having a positive refractive power; a third lens; a fourth lens having a positive refractive power; a fifth lens having a negative refractive power; a sixth lens having a positive refractive power; and a seventh lens with a convex object-side surface. An axial distance TTL from an object-side surface of the first lens to an imaging plane of the optical imaging lens assembly and a half of a maximal field-of-view Semi-FOV of the optical imaging lens assembly satisfy: TTL/Tan(Semi-FOV)
