Blanquefort (French pronunciation: [blɑ̃kfɔʁ]; Gascon: Blancahòrt) is a commune in the Gironde department in Nouvelle-Aquitaine in southwestern France.

This is in line with the very early settlement of all south-western France by pre-historic peoples (e.g. in the Périgord) A Roman military post was set up in the area, to ensure the security of the road to Noviomagus in the Medoc.

During the Plantagenet holding of Aquitaine, the fortifications were expanded into a royal fortress at the end of the thirteenth century by Edward I of England.

During the seventeenth and eighteenth centuries, a number of small chateaux were constructed in the prosperous village by wealthy wine merchants.

From the beginning of the twentieth century, the reliance of the village economy on wine production became a problem as economic crises took their toll.

In the early twenty-first century, as a result of Bordeaux's continuing expansion, new developments have been built to allow the population of Blanquefort to grow further.
