The present disclosure discloses an optical imaging lens assembly. The optical imaging lens assembly sequentially includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, and a seventh lens from an object side to an image side along an optical axis. Each of the first lens, the fourth lens, and the fifth lens has a positive refractive power or a negative refractive power. The second lens has a positive refractive power, and the third lens has a negative refractive power. At least one of the sixth lens and the seventh lens has a negative refractive power. An effective focal length f1 of the first lens and an effective focal length f2 of the second lens satisfy: f2/|f1|
