We report the discovery of a very low mass binary system (primary mass <0.1 M_☉) with a projected separation of ∼5100 AU, more than twice that of the widest previously known system. A spectrum covering the 1-2.5 µm wavelength interval at R∼1700 is presented for each component. Analysis of the spectra indicates spectral types of M6.5 V and M8 V, and the photometric distance of the system is ∼62 pc. Given that previous studies have established that no more than 1% of very low mass binary systems have orbits larger than 20 AU, the existence of such a wide system has a bearing on very low mass star formation and evolution models.
