We argue that the Einstein-Yang-Mills theory presents nontrivial solutions with a NUT charge. These solutions approach asymptotically the Taub-NUT spacetime. They are characterized by the NUT parameter, the mass and the node numbers of the magnetic potential and present both electric and magnetic potentials.=0D The existence of nontrivial Einstein-Yang-Mills solutions with NUT charge in the presence of a negative cosmological constant is also discussed. We use the counterterm subtraction method to calculate the boundary energy-momentum tensor and the mass of these configurations. Also, dyon black hole solutions with nonspherical event horizon topology are shown to exist for a negative cosmological constant.
