The palmar radiocarpal ligament (anterior ligament, volar radiocarpal ligament) is a broad membranous band, attached above to the distal end of the radius, and passing downward to the scaphoid, lunate, triquetrum and capitate of the carpal bones in the wrist.

In addition to this broad membrane, there is a rounded fasciculus, superficial to the rest, which reaches from the base of the styloid process of the ulna to the lunate and triangular bones.

Behind, it is closely adherent to the anterior border of the articular disk of the distal radioulnar articulation.

Some sources break down the components of the ligament as follows: radiolunate, radiocapitate, radiotriquetral, and radioscaphoid.
