The Bretonne Pie Noir is breed of small dairy cattle from Brittany in north-western France.

It originates from Cornouaille and the Pays de Vannes in the départements of Finistère and Morbihan.

Due to its small size, modest requirements, good productivity and ability to exploit poor and marginal terrain, it was well suited to traditional Breton agriculture.

[4][5] The breed was in the past numerous; at the beginning of the twentieth century there were about 500,000.

[2] The milk yield of the Bretonne Pie Noir is about 3500 kg per lactation.
