AB  - The relationship between magnetization and light has been the subject ofintensive research for the past century. Herein, the impact of magnetization onlight polarization is well understood. Conversely, the manipulation of magnetismwith polarized light is being investigated to achieve all-optical control of mag-netism, driven by potential technological implementation in spintronics.Remarkable discoveries, such as the single-pulse all-optical switching of mag-netization in thin films and submicrometer structures, have been reported.However, the demonstration of local optical control of magnetism at the nano-scale has remained elusive. Herein, it is demonstrated that exciting gold nano-discs with circularly polarized femtosecond laser pulses lead to ultrafast, local, anddeterministic control of magnetization in an adjacent magnetic film. This control isachieved by exploiting the magnetic moment generated in plasmonic nanodiscsthrough the inverse Faraday effect. The results pave the way for light-drivencontrol in nanoscale spintronic devices and provide important insights into thegeneration of magnetic fields in plasmonic nanostructures
