A retaining wall block for use to construct a straight, curved or serpentine wall. This block has a front surface, a rear surface and a pair of opposite side surfaces defining four vertical edges. It also has a top surface and a bottom surface . Each of the side surfaces is V-shaped and projects outwardly when seen in top or bottom plan view, thereby giving a general truncated diamond-shaped to the top and botto m surfaces of the block. Each of the opposite side surfaces is provided with t wo integral clippable wings, which extend along the vertical edges of the corresponding side surface, respectively. Each clippable wing projects outwardly from the corresponding side surface so as to extend laterally at least as far away as the corresponding side surface. In use, the wings may be kept or cut depending on the shape selecte d for the wall to be erected.
