The lingual veins are multiple veins of the tongue with two distinct courses: one group drains into the lingual artery; another group drains either into the lingual artery, (common) facial vein, or internal jugular vein.^[1]

The lingual veins are important clinically as they are capable of rapid absorption of drugs; for this reason, nitroglycerin is given under the tongue to patients suspected of having angina pectoris.^{[citation needed]}
