A spinet desk is an antique desk form which has the exterior shape of a slightly higher than usual writing table, fitted with a single drawer under the whole length of the flat top surface. The spinet desk is so named because when closed it resembles a spinet, a musical instrument of the harpsichord family.

This single drawer, however, is a dummy. It is a hinged panel which is meant to be folded in, at the same time as half of the hinged top surface is folded back on to the top of the other half, revealing an inner desktop surface of normal height, with small drawers and pigeonholes in the back. In certain spinet desks the inner desktop surface can be drawn out a few inches, adding working space.

By this capacity of hiding or revealing the main working area the spinet desk could be said to be a smaller, less obtrusive cousin of the rolltop desk and the cylinder desk. Like them, and unlike the secretary desk or the fall front desk, it can be closed up without disturbing too much the paperwork and various documents and implements left on the main desktop surface.
