Giant Names: 190+ Mighty Options for Characters, Pets, Teams & More

Giants demand names that carry weight literally and figuratively. Here’s the ultimate collection, sorted by vibe, use case, and cultural origin.

Editor’s Top Picks

Goliath — The gold standard of giant names. Instantly recognizable, zero explanation needed. Works for dogs, characters, sports teams, and businesses alike.

Colossus — Latin-rooted, carries architectural power. Better than “Big Guy” for any fictional giant who needs to feel ancient and unstoppable.

Gargantu — A trimmed spin on Gargantua (Rabelais’ literary giant). Fresh enough to feel original, familiar enough to land immediately.

Thundra — Female giant energy done right. Norse-adjacent sound without being a direct copy. Strong pick for she-giant characters or fierce team mascots.

Brutus — Short, punchy, historically loaded. Romans used it for serious men. You can use it for a Great Dane or a D&D villain.

Ymir — Norse mythology’s original frost giant. One syllable, impossible to forget, carries genuine mythological weight.

Magna — Latin for “great.” Elegant, gender-neutral, and works across fantasy characters, brands, and pets without feeling overdone.

How to Pick the Right Giant Name

Match the weight of the name to the personality, not just the size.

A Great Dane named “Goliath” hits different than one named “Everest.” Both are giant names — one is warlike, one is majestic. Ask yourself what emotional tone you want first.

Count syllables — rhythm matters.

One-syllable names (Ymir, Bear, Grock) feel punchy and immediate. Two-syllable names (Titan, Atlas, Brutus) are balanced and easy to call out loud. Three+ syllables (Colossus, Gargantua) work better for written characters than for calling a dog at a park.

Check cultural accuracy before using mythological names.

Ymir, Thrym, and Surtr are genuine Norse figures with specific stories. Using them for a lighthearted context is fine — but knowing the backstory makes your choice sharper and avoids accidental misuse.

Ironic names only work with the right personality.

Naming a 180-pound Mastiff “Tiny” is funny when the dog is goofy. It falls flat on an aggressive or stoic dog. Match the irony to the vibe.

For brands and teams, test the plural and possessive forms.

“The Titans” — easy. “The Colossuses” — awkward. “The Goliaths” — works. Always say it out loud in the team context before committing.
