The anchor disc device supports and anchors an umbrella and includes a tube post to receive the free end of the pole of a beach umbrella with an anchor disc portion attached to the free end of the tube post. An end cap is installed in the free end of an extension of the anchor disc portion. The anchor disc portion includes an outwardly extending flange for engagement with sand into which the device is buried to help avoid disengagement of the umbrella from the sand from wind and the like. For removal, the umbrella is rotated in large circular motions to form a cone-shaped hole after which the umbrella and connected anchor disc device can be removed. The anchor disc device can then be detached from the umbrella, if desired.
