Numerous indirect astronomical and cosmological evidences have suggested the existence of dark matter (DM) in the universe. Its existence provides a strong hint that there may be a dark sector, consisting of particles that do not interact with the known strong, weak, or electromagnetic force. Intriguingly, this dark sector might couple to the Standard Model via portals, which include the possibility of axion-like particle, light Higgs boson, dark photon and spin- 1/2 fermions. BESIII experiment has collected the largest data samples at the J/ψ and ψ(3686) on threshold in the world, which provides a clean reaction environment to search for dark sector and new physics. This proceeding summarizes the recent results in the search of dark photon and axion-like particles published by the BESIII Collaboration.
