The ulnar veins are deep paired vessels of the forearm. They arise from the deep venous palmar arch and run superiorly in the deep anterior compartment of the forearm. They terminate in the cubital fossa where they join the radial veins to form the brachial veins.
Along the way they receive several small tributaries from the adjacent muscles.
This article will discuss the anatomy and function of the ulnar veins.

The ulnar veins are two major deep paired veins of the forearm, along with the radial veins. They are formed from the deep palmar venous arch and usually course as two anastomosing veins (venae comitantes) that accompany the ulnar artery.
The ulnar veins run proximally along the medial aspect of the deep anterior compartment of the forearm. Along their course, they receive numerous tributaries that accompany the respective branches of the ulnar artery.
The ulnar veins terminate in the cubital fossa where they join the radial veins to form the paired brachial veins.
