Luna

Luna comes from Latin, meaning 'moon.' In Roman mythology, Luna was the goddess of the moon, depicted driving a silver chariot across the night sky — a counterpart to the sun god Sol. The name carries both celestial imagery and a quiet, nocturnal grace. Its two soft syllables feel naturally musical, which gives it a lyrical quality that resonates whether you are calling across a yard or whispering to a pet curled up beside you.

Luna has climbed to #3 in our dataset with 6,571 pets carrying the name, and its rise mirrors a broader cultural love for celestial and nature-inspired names over the past decade. The name works for any companion with a calm, luminous presence — the pet who seems to glow a little quieter and more beautifully than the chaos around them. Luna also benefits from extraordinary pop culture momentum: it is the name of Harry Potter's beloved character Luna Lovegood, and it has become one of the most searched pet names online year after year. There is a timeless, slightly mysterious quality to Luna that makes it feel both fashionable and enduring — not a trend, but a permanent fixture in the top tier of pet naming.
