The femoral vein (latin: vena femoralis) is a large blood vessel of the thigh formed by the popliteal vein.
The femoral vein arises at the adductor canal as the continuation of the popliteal vein. The femoral vein ends at the inferior margin of the inguinal ligament, becoming the external iliac vein.
The main tributaries of the femoral vein are the popliteal vein, the deep vein of the thigh and the great saphenous vein.
The femoral vein accompanies the femoral artery in the femoral sheath.
The femoral vein drains blood from the muscles and skin of the thigh.
