Vulnerable Native Breeds are a group of dog breeds originating in the United Kingdom and Ireland, and identified by The Kennel Club (KC) as having annual registration numbers of 300 puppies or fewer.

 It was a joint project, with the KC working with the British and Irish Native Breeds Trust, later to be known simply as the Native Dog Breeds Trust.
