A vehicle roof of a convertible with at least one front roof part, a rear roof part that is movable between a closed position over the vehicle interior and an open position in which it is stowed in a rear stowage space, and a rear window which is pivotably supported on the rear roof part. In the open position in the stowage space, the window is raised relative to the rear roof part. For improved actuation of the rear window, a holding mechanism keeps the rear window in its closed position on the rear roof part and when the rear roof part is being stowed, releases the rear window to swing relative to the rear roof part. A support is located in the stowage space and supports the rear window while the rear roof part is lowered into its stowage position.
