  A brief overview is presented of the signatures for several different models
with extra dimensions at CLIC, an $e^+e^-$ linear collider with a center of
mass energy of 3-5 TeV and an integrated luminosity of order 1 $ab^{-1}$. In
all cases the search reach for the resulting new physics signatures is found to
be in the range of $\simeq$15-80 TeV.
