The ovarian artery ( lat. "Ovarian artery") is a paired, from the abdominal aorta springing artery in female mammals which the ovary ( ovary supplied). It corresponds to the testicular artery of male individuals.

The exit of the arteria ovarica takes place below the renal artery ( arteria renalis ). The vessel runs together with the ovarian vein and sympathetic nerve fibers - in humans in the ligamentum suspensorium ovarii and in animals in the mesovarium to the ovary.

A branch for the fallopian tube ( ramus tubarius ) and, in many mammals, also for a small part of the uterus ( ramus uterinus ) extends from the ovarian artery before it enters the ovary .

In most mammals, the ovarian vein is the main outflow for the uterus, as the uterine vein is usually small or even absent. It opens into the renal vein on the left and directly into the inferior vena cava on the right (referred to as the caudal vena cava in animals ).
