It is now well established and accepted that roughly 25% of the total mass-energy density of the Universe is in the form of non-relativistic particles. That these particles, referred to as Dark Matter, have remained a mystery has served as motivation for the design and implementation of increasingly ingenious and far reaching experiments in an attempt to identify and understand them. This talk will review various ongoing Dark Matter direct detection searches with a focus on the variety of techniques and implementation used to both detect the rare Dark Matter interactions as well as reject the vast number of background events from cosmic ray and radioactive backgrounds. Such experiments naturally complement accelerator and astrophysical based Dark Matter searches, and are already sensitive to and are able to reject certain models of supersymmetry. With the increases in sensitivity projected over the next few years we may even be able to detect these elusive particles.
