We announce the discovery of a new early‐type, double‐lined spectroscopic binary in the LH 54 OB association in the Large Magellanic Cloud. We present a V light curve and radial velocities. We investigate the possible configurations of the system, concluding that it probably contains the most massive star measured at the present, with a mass of the order of 100 M ⊙ , while its companion has approximately 50 M ⊙ .
