The old nova NQ Vul (1976) was observed in the J = 2-1 rotational transition of (C-12)O. A broad, low-intensity feature is seen, centered at velocity 26 km/s relative to the local standard of rest, FWHM of about 80 km/s and peak antenna temperature 63 mK. The central V(LSR) is consistent with the distance (1.2 + or - 0.5 kpc) and galactic coordinates of NQ Vul, and it is concluded that the CO is associated with the NQ Vul system. Possible origins of this material are discussed, and it is suggested that it represents material ejected by the NQ Vul system prior to its 1976 outburst.
