This communication proposes a new method to shrink a rectangular waveguide resonator (RWR) using metallic mushroom metamaterials. One such a small RWR is numerically demonstrated to resonate in the $\boldsymbol{L}-\mathbf{band}$ The electric volume is only $\mathbf{0}.\mathbf{262}\boldsymbol{\lambda}\times \mathbf{0}.\mathbf{175}\boldsymbol{\lambda}\times \mathbf{0}.\mathbf{044}\boldsymbol{\lambda}$. The quality-factor for the compact RWR maintains at a high level of nearly 1016, resulted from the low loss property of metallic metamaterials.
