A chain alignment tool to assist the alignment of a chain sprocket with respect to its chain. The tool is placed over a sprocket at a point where its chain tangentially contacts the sprocket. The tool is tightened against the sprocket and becomes aligned with the sprocket. The tool has an attached pointer which extends outwardly in a direction parallel to the surface of the sprocket. The end of the pointer should align with the chain if the chain is in alignment with the sprocket.
