Daftar julukan kota di Kentucky ini mengandung samaran, julukan, dan slogan yang disematkan kepada beberapa kota di Kentucky (resmi dan tidak resmi) oleh pemerintah kota, masyarakat setempat, orang asing, badan pariwisata, atau kamar dagang. Julukan kota berperan sebagai perintis identitas lokal, membantu orang asing mengenali masyarakat setempat, atau mengajak orang berkunjung karena julukannya khas; mengangkat martabat daerah; dan mempersatukan masyarakat.[1] Julukan dan slogan yang berubah menjadi "ideologi atau mitos" baru[2] juga diyakini memiliki potensi ekonomi.[1] Potensi ekonominya sulit diukur,[1] tetapi ada beberapa kota yang memakai slogan baru untuk memasarkan/mencitrakan diri dan memanfaatkan potensi ekonomi tersebut.[2]
