We present the results of a spectroscopic campaign on the early-type double-lined binary HD 64315. The radial velocity curve was calculated using a fit to model atmospheres, considering two components. After this, we find strong evidences suggesting that HD 64315 is composed of two binary systems, one of them eclipsing. We re-analyse HD 64315 assuming four components and estimate its stellar parameters.
