Particle production at the end of a first-order electroweak phase transitionmay be rather generic in theories beyond the standard model. Dark matter maythen be abundantly produced by this mechanism if it has a sizable coupling tothe Higgs field. For an electroweak phase transition occuring at a temperatureT_EW ~ 50-100 GeV, non-thermally generated dark matter with mass M_X > TeV willsurvive thermalization after the phase transition, and could then potentiallyaccount for the observed dark matter relic density in scenarios where a thermaldark matter component is either too small or absent. Dark matter in thesescenarios could then either be multi-TeV WIMPs whose relic abundace is mostlygenerated at the electroweak phase transition, or "Baby-Zillas" with mass M_GUT>> M_X >> v_EW that never reach thermal equilibrium in the early universe.
