Abstract: A chalk holder for coupling to a pool cue comprising, in combination a first holder component having cylindrical side walls, an open rearward end and a closed forward end, the forward end having a central hole with a screw for mounting to the rear end of a pool cue with the bumper removed; a second holder component having cylindrical side walls, an open forward end and a closed rearward end, the diameter of the side walls of the second holder component being less than the diameter of the cylindrical side walls of the first holder component to allow its reciprocal movement there within for thereby defining a cylindrical volume between the cylindrical walls of the second holder component, the closed forward end of the first holder component and the closed rearward end of the second holder component; coupling elements to releasable join the first holder component and second holder component, such elements including a pair diametrically opposed, interiorally directed, radial pins secured to the cylindrical side w
