A Handheld All-Terrain Chalker of the present invention is designed to create straight chalk lines on all types of surfaces. The Handheld All-Terrain Chalker works independent of the surface in which the chalk lines are to be drawn and are unaffected by the variations of the surface. The Handheld All-Terrain Chalker includes a chalk hopper and a removable ergonomic handle. The chalk hopper is a semi-circular bucket having a storage container integrally formed with a dispenser. The storage container has an opening to allow the insertion of chalk. The dispenser is formed with a bottom having circular perforations or slotted openings to allow chalk to be dispensed to draw the chalk lines. To control the amount of chalk being dispensed and the width of the chalk line, a gasket or an adjustable chalk line plate is used to regulate the opening of the dispenser.
