An imaging lens assembly is disclosed in the present disclosure. The imaging lens assembly includes, in order from an object side to an image side, a stop; a first lens having a positive refractive power, a convex object-side surface and a convex image-side surface; a second lens having a negative refractive power and a convex and meniscus shaped image-side surface; a third lens having a negative refractive power, an image-side surface being concave at a paraxial region and being convex and meniscus shaped at a peripheral region, and an object side-surface being concave at the paraxial region; the image-side surface of the third lens having an inflection point. At least one of the surfaces of three lenses is aspheric, f is a focal length of the imaging lens assembly; f1 is a focal length of the first lens and the imaging lens assembly satisfying following condition: 0
