Bernard V of Astarac

Bernard V (1279–1328 or 1329) was Count of Astarac, ruling from his father Centule III's retirement in 1294 and in his own right from 1301. In 1294 he married Mathe de Foix, who bore him Bernard and Amanieu. He later married Tiburge de L'Isle-Jourdain, widow of Gautier du Fossat.

His eldest son Bernard predeceased him; Bernard V last appeared in documents in 1328 and died that year or the next, leaving the succession to his grandson Centule IV.
