A spectroscopic and photometric study of the late-type contact binary BX And is presented. Three V light curves have been obtained between 1985 and 1988 as well as the first radial-velocity data for this system during 1987. The first IR light curves in the J and K pass-bands are also presented. A full analysis of these data and two other light curves obtained in 1976 and 1981/1982 are given which suggest that BX And is a marginal-contact binary with a hot spot on the secondary component which is approximately 1200 K hotter than the surrounding photosphere and approximately 72 deg in diameter covering 20 percent of the star.
