Weyl and Dirac semimetals are three dimensional phases of matter with gapless\nelectronic excitations that are protected by topology and symmetry. As three\ndimensional analogs of graphene, they have generated much recent interest. Deep\nconnections exist with particle physics models of relativistic chiral fermions,\nand -- despite their gaplessness -- to solid-state topological and Chern\ninsulators. Their characteristic electronic properties lead to protected\nsurface states and novel responses to applied electric and magnetic fields.\nHere we review the theoretical foundations of these phases, their proposed\nrealizations in solid state systems, recent experiments on candidate materials,\nas well as their relation to other states of matter.\n
