Abstract
BESIII experiment has collected the world's largest data sets at the $J/\psi$ and $\psi(3686)$ resonances. The huge clean data sample provide an excellent chance to search for new physics. In this proceeding, we review some recent search results of invisible decays from BESIII.
These include the quarkonium invisible decays $\omega\to invisible$, $\phi \to invisible$ and $J/\psi\to\gamma + invisible$; and the first search for the $\Lambda \to invisible$ in the baryon sector.
