style="font-size:14.0pt;font-family:"Times New
Roman","serif"">The search for dark matter and
new forces mediated by sub-GeV particles with very weak coupling
to matter (“dark forces”) is an emerging frontier in fundamental
physics. I will present the theoretical motivations for dark
forces and their possible connections to dark matter and the
anomalous magnetic moment of the muon. I will also discuss
strategies, results, and prospects for searches at high-energy
colliders, flavor factories, and dedicated fixed-target
experiments. I will focus particularly on the near-term program
of searches for dark forces at Jefferson Lab, including APEX in
Hall A and HPS in Hall B, and I will briefly describe
opportunities to directly search for dark matter at Jefferson
Lab in the future.</span></p>
