The stand comprises a base member, a cup member, and a means for selectively adjusting and locking the tree trunk in the stand in a fixed angular orientation. The tree stand of the present invention allows a tree trunk placed in the stand to be easily levelled so that the tree is aesthetically pleasing, appearing perpendicular to a floor surface.
