We summarize the main features of several dark matter candidates in
extra-dimensional theories. In particular, we review Kaluza-Klein (KK)
gravitons in universal extra dimensions and branons in brane-world models. KK
gravitons are superWIMP (superweakly-interacting massive particle) dark matter,
and branons are WIMP (weakly-interacting massive particle) dark matter. Both
dark matter candidates are naturally produced in the correct amount to form
much or all of dark matter.
