Dileptons are among the most essential tools for investigating the strongly interacting matter created in ultra-relativistic heavy-ion collisions. Once produced, leptons, as well as photons, are not affected by the strong interaction. Dileptons have an advantage over photons in that they have an additional kinematic dimension, their invariant mass. Therefore, different kinematics of lepton pairs (mass and transverse momentum ranges) can selectively probe the properties of the matter throughout the whole evolution. In this talk, I will review the most recent dilepton results at STAR. Future perspectives of dilepton measurements will also be discussed.
