An edging block for miniature golf courses includes a top section that has a top surface that has a trapezoidal shape and four substantially rectangular walls depending down and at substantially right angles to the top surface. Each edging block has a bottom section with a congruent trapezoidal shape. There are two non-parallel sides, each of which has a protrusion and a receiver situated such that when one of the non-parallel sides aligns with a second non-parallel side of a second edging block, the protrusion of the one of the non-parallel sides inserts into the receiver of the second parallel side of the second edging block and, a protrusion of the second parallel side of the second edging block inserts into the receiver of the one of the non-parallel sides. There is also a feature for holding the top section to the bottom section.
