Bertrand VI (c. 1417 - 26 September 1497) was lord of La Tour and count of Auvergne from 1461 until his death.

He was also count of Boulogne from 1461 to 1477, when he exchanged that title for the county of Lauragais, which he held for the remainder of his life.

Bertrand was part of Charles VII of France's entourage from 1441 to 1451,[1] during the last stages of the Hundred Years' War.

This allowed Louis XI to reconquer the county of Boulogne, which had been occupied by burgundian forces.

[2][3][4] Bertrand died in 1497 and was succeeded by his first-born son: John IV, Count of Auvergne.
