A cup holder with an adjustable depth includes: a cup-holder base, having at least one accommodation hole; a fixed cup holder, fixed in the accommodation hole of the cup-holder base; and a moveable cup holder, moveably sleeved over the fixed cup holder and capable of rotating around the fixed cup holder to ascend and descend, where during ascending and descending of the moveable cup holder, an inner cavity of the moveable cup holder and an inner cavity of the fixed cup holder jointly define a container placement hole for placement of containers of different heights. The present invention solves the problem that containers of different heights placed in the cup holder easily fall out when the automobile is accelerating, hard braking or travelling over uneven road surfaces. In addition, after the moveable cup holder descends to the lowest position, the moveable cup holder can completely overlap the fixed cup holder, so that the entire cup holder has a small height and is therefore suitable for installation in a thin interior trim part of the automobile, for example, in the armrest at the rear seat, thereby saving interior trim space in the automobile.
