In this talk it is shown how to formulate gauge theories relevant to particle physics on a noncommutative spacetime. One of the key problems is to understand how to formulate symmetries on a noncommutative spacetime. We shall explain how to formulate SU(N) gauge symmetries and Lorentz symmetry on these spaces. We then explain how to quantize field theories formulated on such a spacetime and apply our results to QED and GUT theories. We then describe experimental bounds on the scale for spacetime noncommutativity.
