  Hidden theories coupled to the SM may provide emergent (dark) vectors, that
are composites/bound-states of the hidden fields. This is motivated by
paradigms emerging from the AdS/CFT correspondence but it is a more general
phenomenon. We explore the general setup and find that UV interactions among
currents or charged fields give rise to emergent vectors in the IR. We study
the general properties of such vectors and argue that they can be generically
different from fundamental dark photons that have been studied so far.
