The triangular lattice antiferromagnet (TLAF) has been the standard paradigm of frustrated magnetism for several decades. The most common magnetic ordering in insulating TLAFs is the 120$$^{circ}$$ structure. However, a new triple-$$mathbf{Q}$$ chiral ordering can emerge in metallic TLAFs, representing the short wavelength limit of magnetic skyrmion crystals. We report the metallic TLAF Co$$_{1/3}$$TaS$$_{2}$$ as the first example of tetrahedral triple-$$mathbf{Q}$$ magnetic ordering with the associated topological Hall effect (non-zero $$sigma_{xy}(mathbf{H}=0)$$). We also present a theoretical framework that describes the emergence of this magnetic ground state, which is further supported by the electronic structure measured by angle-resolved photoemission spectroscopy. Additionally, our measurements of the inelastic neutron scattering cross section are consistent with the calculated dynamical structure factor of the tetrahedral triple-$$mathbf{Q}$$ state.
