A bearing arrangement for a wind turbine for supporting a drivetrain on a tower of the wind turbine includes a base plate which is attachable to the tower and has a main bearing section for rotatably supporting a rotor shaft of the drivetrain and for supporting forces of the rotor shaft. The main bearing section introduces radial forces relative to a rotor shaft axis into the base plate and allows axial displacements along the rotor shaft axis. The radial forces have components in a transverse and a vertical direction. A bearing housing receives and supports parts of the drivetrain, and a torsion bearing unit supports a torsional moment about the rotor shaft axis, which is applied to the bearing housing by the drivetrain. The torsion bearing unit introduces axial forces in the direction of the rotor shaft axis and torsional moments about the rotor shaft axis into the base plate.
