The Advanced Telescope for High-energy Astrophysics (Athena) is an X-ray observatory proposal to be submitted to the ESA call for mission concepts for the science theme "The Hot and Energetic Universe". To be launched in 2028, Athena will provide transformational capabilities in terms of angular resolution, effective area, spectral resolution, and grasp, that will make it the most powerful X-ray observatory ever flown. I will discuss various synergies between the Athena mission and the SKA telescope.
