From numerous radial velocities obtained at KPNO and Fairborn Observatory, we have determined the orbital elements of the composite spectrum triple system HD 207651. This system consists of a broad-lined A8 V star and an unseen M dwarf companion in a 1.470739days orbit. Variations of the center-of-mass velocity of this short-period system and velocity variations of a narrow-lined F7: V star have an orbital period of 724.1days or 1.98yr and an eccentricity of 0.39. The revised Hipparcos parallax, corresponding to a distance of 255pc, appears to be too small to yield consistent properties. Instead, we adopt a distance of 150pc.
