A new force mediated by a new vector boson (a "dark photon") with mass in the MeV to GeV range and with very weak coupling to ordinary matter appears naturally in many theoretical models. A dark photon can explain the discrepancy between the predicted and the experimentally observed value for the muon anomalous magnetic moment (g-2) and could, if it couples to dark matter, explain data from several dark matter search experiments. This talk will review the motivation for dark photons and present a broad array of searches. These include high-intensity e+e- colliders such as BaBar and BELLE; new high-intensity electron fixed-target experiments such as APEX, HPS, and DarkLight at Jefferson Laboratory; high-intensity proton fixed target experiments at, for example, Fermilab; and searches at the Tevatron and LHC.
