  Many extensions of the Standard Model introduce a new type of
weak-interacting degrees of freedom. These models are motivated by the results
of recent experimental anomalies. Typical models, such as Next-to-Minimal
Supersymmetric Standard Model and Light Hidden Dark-sector Model, introduce the
possibilities of low-mass Higgs and dark bosons. The masses of such particles
are expected to be few GeV and thus making them accessible at BESIII
experiment, an $e^+e^-$ collider experiment running at tau-charm region. This
report summarizes the recent results of low-mass Higgs and dark bosons searches
at BESIII.
