The Kennel Club ("KC") is the official kennel club of the United Kingdom. It is the oldest recognised kennel club in the world. Its role is to oversee various canine activities including dog shows, dog agility and working trials. It also operates the national register of pedigree dogs in the United Kingdom and acts as a lobby group on issues involving dogs in the UK. Its headquarters are on Clarges Street in Mayfair, London, with business offices in Aylesbury.

The Kennel Club registration system divides dogs into seven breed groups. The Kennel Club Groups are: Hound group, Working group, Terrier group, Gundog group, Pastoral group, Utility group and Toy group. As of 2020, the Kennel Club recognized 218 breeds of dog.The Kennel Club licenses dog shows throughout the UK, but the only dog show it actually runs is Crufts. The show has been held since 1928 and attracts competitors from all over the world. It is held every March at the NEC, Birmingham, and includes the less formal Scruffts show for crossbreed and mixed-breed dogs. The Kennel Club also holds the Discover Dogs event in London every autumn.

The KC is a non-member partner with the Fédération Cynologique Internationale.
