Tolkien named trolls exactly once: Tom, Bert, and William Huggins, three ordinary English names given to comic effect in The Hobbit. Everywhere else, trolls go by type only, cave-troll, mountain-troll, or the Black Speech class name Olog-hai. This generator fills that silence with an invented register of its own: short, thudding two-syllable given names built from hard consonant clusters, paired with a plain-English epithet that says exactly what the troll breaks or carries.
How the name is built
The hard opening cluster that starts the given name, like Krom- or Hrud-. It carries the raw monster sound, the crack or growl you hear first.
The closed or mumbling syllable that finishes the given name, like -bog or -nak. It gives the name its blunt, dropped-boulder stop.
An optional plain-English compound tacked on after the given name, like Rockbreaker or Slowmaw, that says exactly what the troll smashes, carries, or is too dim to avoid doing.
Do's and don'ts
Do
- Keep the given name to two syllables with a hard opening cluster, like Krom- or Hrud-, so it lands heavy and fast.
- End the given name on a closed, blunt sound (Krombog, Hrudnak) or a mumbling double vowel (Throgga, Brugga) rather than a light, open vowel.
- Pick an epithet that names one concrete thing the troll does or breaks, such as Rockbreaker or Oakbrow, not a rank or title.
Don’t
- Don't reuse Tom, Bert, or William Huggins directly. That trio is a specific joke tied to three characters, not a naming formula to copy.
- Don't reach for flowing, vowel-heavy syllables the way you would for an elf name. Trolls should sound like a boulder dropping, not a word being sung.
- Don't give a troll a title of honor or lineage. Every approved epithet in this generator is a physical description, not a rank.
- Given name first, epithet second, and the epithet is optional: Krombog on its own reads fine, Krombog Rockbreaker reads bigger.
- Stack hard consonant clusters (gr, kr, dr, thr, hr) at the start of the given name to do the work an elvish or human name would do with vowels.
- Reserve the -a ending (Throgga, Brugga) for a slightly slower, more mumbling troll and the hard consonant endings (-bog, -nak, -lash) for a sharper, more violent one.
Famous names, decoded
Tom, Bert, and William Huggins
The Hobbit, chapter 2, Roast Mutton
Tolkien's only individually named trolls got deliberately mundane English names, not invented ones, because the joke was a stone-eating monster with a name that sounds like a delivery driver. This generator does the opposite on purpose: it invents a harsh new register instead of recycling Tom, Bert, and William, since their names only work as a one-off gag.
Olog-hai
The Lord of the Rings, Appendix F
Sauron's sun-hardy troll breed gets a group label, olog meaning troll plus the folk-suffix hai, and no Olog-hai is ever named as an individual. It shows Tolkien using personal names for comic effect early on and pure anonymity for menace later, which is why this generator leans toward names that sound like a threat rather than a punchline.
The cave-troll of Moria
The Fellowship of the Ring, A Journey in the Dark
Described in detail, greenish hide, a chain, a mangled foot, but called only the troll throughout. This confirms that outside the Hobbit's comic trio, Tolkien's default for trolls is silence, which is exactly the gap this generator's invented names are built to fill.

Frequently asked
Did Tolkien actually give trolls names?
Only three, and only once: Tom, Bert, and William Huggins in The Hobbit. Every other troll in the legendarium, including the cave-troll of Moria, the mountain-trolls at Minas Tirith, and the snow-trolls near Helm's Deep, appears only as an unnamed individual or as part of the class name Olog-hai.
What does Olog-hai mean?
It is Black Speech for troll-folk: olog means troll, and hai is the same folk or host suffix used in Uruk-hai. It labels Sauron's stronger, sun-resistant breed of trolls as a group, never as one troll by name.
Why don't this generator's troll names sound like Tom, Bert, and William?
Tom, Bert, and William Huggins is a one-off joke built from ordinary English names and Cockney-flavored dialogue tied to three specific characters, not a system you can generate more names from. This generator instead builds its own harsh, guttural register, hard consonant clusters and blunt two-syllable shapes, so it can produce many distinct trolls without just reusing Tolkien's own characters.
Is there an Elvish word for troll?
Yes, the Sindarin word is torog, plural teraig. It appears in the place name Rhudaur, which Tolkien translated as Troll-shaw, but it names the kind of creature and is never used as anyone's personal name in the text.
Should a troll's epithet be a title of rank or a physical description?
Physical description, always. Every approved epithet in this generator, things like Rockbreaker, Slowmaw, or Oakbrow, names a concrete action or trait rather than a rank or honor, matching how Tolkien's own trolls are defined by size and violence rather than status.
