Abstract: We point out that pseudomoduli - tree-level flat directions that oftenaccompany dynamical supersymmetry breaking - can be natural candidates forTeV-scale dark matter in models of gauge mediation. The idea is general and canbe applied to different dark matter scenarios, including but not limited tothose of potential relevance to recent cosmic ray anomalies. We describe therequirements for a viable model of pseudomoduli dark matter, and we analyze twoexample models to illustrate the general mechanism - one where thepseudomoduli carry Higgsino-like quantum numbers, and another where they are SMsinglets but are charged under a hidden-sector $U1-$ gauge group.
