The discovery of an eclipsing binary (BD-3 deg 5357) which contains a hot subdwarf (temperature of approximately 40,100 K) is reported. Ultraviolet data, photometric observations, and spectroscopic results are combined to produce a set of tentative models of the system. These show that the cool subgiant (G8 III) is considerably smaller than its Roche radius. A representative model gives an absolute visible magnitude of + 4.7 and log g of 6.1 for the subdwarf. The possible evolutionary history of this object is briefly considered.
