We have carried out the magnetoresistance measurements in β″-(BEDT-TTF)2AuBr2. SdH signals with at least two fundamental frequencies of 41.5T and 139T are observed for H//b*-axis. The angular dependence of both frequencies shows that the Fermi surfaces are cylindrical. An anomalous resistance maximum is found at about 9.5K when magnetic fields above 4T are applied parallel to the b*-axis, although no anomaly is observed for fields in the ac-plane.
