The present disclosure discloses an optical imaging lens assembly. 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, a fourth lens, a fifth lens, a sixth lens and a seventh lens. The first lens has a positive refractive power. An image-side surface of the second lens and an image-side surface of the seventh lens are convex surfaces. A total effective focal length f of the optical imaging lens assembly and an entrance pupil diameter EPD of the optical imaging lens assembly satisfy: f/EPD≤1.90.
