Weakly Interacting Massive Particles (WIMPs) are one of the leading candidates for the dark matter of the Universe. Dark matter searches include collider, direct and indirect detection experiments. I briefly discuss how the La rge Hadron Collider can constrain theories of dark matter. I then discuss 2 cosmological probes of dark matter: (i) The cosmic microwave background and (ii) Radio observations of the nearby dwarf galaxies.
