威尔斯柯基犬（Welsh Corgi，又名哥基犬）是一种原产于英国威尔斯的狗，人们认为牠是源自维京人带来威尔斯的瑞典牧羊犬(Swedish Vallhund)；柯基在威尔斯文中的意思是矮犬。

威尔斯柯基犬平均肩高大约25至30公分、重约15公斤，原本培养来放牧牛羊，低矮的身材让他们免于被牛只踢到。柯基犬是主动的犬只并且相当的聪明，是绝佳的伙伴动物，并且在牧羊竞赛跟犬只敏捷竞赛中是出色的参赛者。

威尔斯柯基犬通常分成两个品种：卡提根（Cardigan） 跟潘布鲁克（Pembroke）。1934年起美国育犬协会承认他们为不同的品种。卡提根是两种中较大的、有着较大的圆耳跟狐狸般下垂的尾巴；潘布鲁克的特征则是较尖的耳朵跟较小的身材。潘布鲁克的尾巴传统上是断尾成平贴的兔尾巴，让他们看起来像无尾。两种的毛色皆非常多样，但在品种间仍有一些差别。

The Welsh Corgi (/ˈkɔːrɡi/; Welsh for "dwarf dog") is a small type of herding dog that originated in Wales. Two separate breeds are recognized: the Pembroke Welsh Corgi and the Cardigan Welsh Corgi. Historically, the Pembroke has been attributed to the influx of dogs alongside Flemish weavers from around the 10th century, while the Cardigan is attributed to the dogs brought with Norse settlers, in particular a common ancestor of the Swedish Vallhund. A certain degree of breeding between the two types has been suggested to explain the similarities between the two.
