The present invention is applicable to the field of door and window technologies, and provides a top-hung casement window, including a window frame, a casement sash, and a hinge assembly. The hinge assembly includes a first hinge, a second hinge, a pivot, a connecting piece, a swing part, and a vertical limiting part. During the turning of the casement sash, the swing part swings only around the vertical limiting part, with a limited motion space. Therefore, the swing part and the casement do not shake easily. When the casement sash is open, the position of the vertical limiting part and casement sash does not change. Because all force of gravity of the casement sash is transferred to the window frame through the vertical limiting part, the bottom of the casement sash does not rub the window frame, avoiding generation of noise and abrasion of components of the hung window.
