Keira — an Irish name from Ciara, meaning "dark" or "black" — got a significant visibility boost from Keira Knightley, whose film career spanning Pirates of the Caribbean and Pride and Prejudice in the 2000s made this spelling variation recognizable internationally. On a female pet, it has elegance with a slight edge: refined but not fragile.
The Keira Knightley Association
Knightley's particular brand of on-screen presence, period-drama grace combined with genuine scrappiness, defines how the name reads culturally. A pet named Keira belongs to the same aesthetic register as pets named Audrey, Grace, and Vivienne: named after women who project composed authority. Whippets and slender, elegant sighthounds suit the association beautifully.
