A wind turbine nacelle (50) which comprises a frame (54) and a drive train which comprises a gearbox (55). The nacelle (50) has a rotor attached thereto and comprises a rotor hub (52), with one or more blades (53), which supported by a rotor bearing(s) (56) located on a tubular part (57) at an end of the frame (54) furthest from the tower (51). The gearbox (55) comprises a gearbox housing (58), not constituting part of the frame (54), which is rigidly and axially connected to the frame (54) by a gearbox flange (66) such that a side of the gearbox flange (66), furthest from the gearbox input side (I), is connected to an end of the frame flange (67) furthest away from the tower (51). An input shaft (76) of the gearbox (55) is connected to the rotor hub (52) via a separate connection part (77).
