The posterior interventricular sulcus or posterior longitudinal sulcus is one of the two grooves that separates the ventricles of the heart and is on the diaphragmatic surface of the heart near the right margin. The other groove is the anterior longitudinal sulcus, situated on the sternocostal surface of the heart, close to its left margin.

In it runs the posterior interventricular artery and middle cardiac vein.
