Results of the first radio interferometric observations of the radio galaxy 3C 111 at decameter wavelengths are presented. The observations were obtained using the URAN-1 interferometer. A simple model for the radio-brightness distribution of this source at 25 and 20 MHz has been determined. The general properties of the best-fit three-component model at these wavelengths are similar to those observed at centimeter wavelengths; the overall maximum sizes and position angles of the structures are virtually identical. However, there are appreciable differences; in particular, the decameter angular sizes of the outer components are considerably larger, and the relative contribution of the central component (which coincides with the optical galaxy) is much less.
