The inferior anastomotic vein, also known as the vein of Labbé, is one of several superficial cerebral veins on the human brain. It was named after the 17th century French surgeon Charles Labbé, the uncle to the surgeon and politician Léon Labbé. It crosses and anastomoses at its two ends with the middle cerebral vein and the transverse sinus. The appearance and structural anatomy of the vein itself appears to be highly variable within the human population.
The vein drains its adjacent cortical regions gathering tributaries from minor veins of the temporal lobe.
