The linea semilunaris is a curved tendinous line placed one on either side of the rectus abdominus.

Each corresponds with the lateral border of the rectus, extends from the cartilage of the ninth rib to the pubic tubercle, and is formed by the aponeurosis of the internal oblique at its line of division to enclose the rectus, reinforced in front by that of the external oblique, and behind by that of the transversus.
