The invention relates to a mirror cabinet, and provides the mirror cabinet with a cabinet door opened and closed in a door swinging mode so that space occupied in the cabinet door opening and closing process can be narrowed. Meanwhile, objects in the mirror cabinet can be taken when the cabinet door is partially opened, and after the cabinet door is opened, people can look into a mirror even when standing right in front of the mirror cabinet. The mirror cabinet comprises a cabinet body 1, the cabinet door 2 and connection supports 3. Each connection support 3 is of a multi-connection-rod structure and composed of a slide rail connection rod 4, a second connection rod 5, a third connection rod 6 and a sliding connection device 7, wherein one end of the slide rail connection rod 4 is hinged to one end of the second connection rod 5, the other end of the second connection rod 5 is hinged to one end of the third connection rod 6, the other end of the third connection rod 6 is hinged to the sliding connection device 7, the sliding connection device 7 is arranged on the slide rail connection rod 4 and can slide along a slide rail, and the slide rail connection rod 4 is arranged on a transverse partition plate of the cabinet body 1. The cabinet door 2 is fixedly connected with the third connection rods 6 and is limited by the connection supports 3 to revolve relative to the cabinet body 1. Meanwhile, the cabinet door is opened and closed in a reverse-rotation swing mode.
