$$^{69,71}$$Ga NMR has been measured in the metallic ferromagnet UGa$$_2$$. The $$T$$-dependence of the internal field at the Ga site has been determined and is found to coincide with that of the spontaneous magnetization. The electric field gradient (EFG) and transferred hyperfine coupling constant at the Ga site are found to be modified in the ferromagnetically ordered state, presumably due to a modification of the $$5f$$ electronic state caused by the ferromagnetic ordering. The spin-lattice relaxation rate $$1/T_1$$ is enhanced due to ferromagnetic fluctuations around $$T_c$$. The 5$$f$$ magnetic moments are considered to be nearly localized in UGa$$_2$$, in spite of good metallic conduction.
