The disclosure provides an optical imaging lens, a camera module and a mobile phone. The optical imaging lens sequentially includes: a first lens having a positive refractive power, a convex object side surface and a concave image side surface; a second lens with a negative refractive power; a third lens with a positive refractive power; a fourth lens with a negative refractive power, wherein an object side surface of the fourth lens is concave at the paraxial region, and an image side surface of the fourth lens is convex at the paraxial region; a fifth lens with a negative refractive power, an image side surface of the fifth lens being concave at the paraxial region; a sixth lens with a positive refractive power; and a seventh lens with a negative refractive power.
