Goblin (Tolkien)
The Goblin alphabet is the fictional script of the goblins (orcs) in the works of J.R.R. Tolkien (1892-1973). Appearing in The Hobbit (1937) and developed across The Lord of the Rings (1954-1955), it is derived from the Cirth — the elven runes invented by the Sindar in the First Age — but simplified and brutalised in the hands of Sauron and Saruman’s soldiers.
Where Tengwar (the noble elven alphabet created by Fëanor) and Cirth (the elven runes) are calligraphic and learned, Goblin is rough, designed to be carved quickly on stone, metal or leather — consistent with the warrior and utilitarian culture of the orcs of Mordor and Isengard. The Latin ↔ Goblin mapping was reconstructed by the Tolkien community (Tolkien Gateway, The Lord of the Rings Wiki) then stabilised by the Middle-earth roleplaying games (MERP, Lord of the Rings Online, War of the Ring). 26 Latin letters, no digits.
How does the alphabet work?
The cipher relies on a monoalphabetic substitution: each cleartext letter is replaced by the corresponding Goblin glyph. Same mechanic as the Caesar cipher (~50 BC), except the “key” is an image table from a major literary fantasy universe.
The table holds 26 glyphs for the 26 Latin letters (no digits). The glyphs are deliberately angular and brutal, knife-carved rather than pen-drawn, to reflect the orc culture in the lore.
Cryptographic strength: low. Monoalphabetic substitution → trivial frequency analysis. But that was never the goal: it’s a narrative device that colours orc inscriptions (“bear the Ring, slave of Mordor!”) in the films and games.
Historical and modern usage
- Tolkien’s works — The Hobbit, The Lord of the Rings.
- Middle-earth roleplaying games — MERP, LOTRO, War of the Ring.
- Tolkien community — fan art, orc cosplay, tattoos.
- Literary pedagogy — link to historical Scandinavian runes.

- Dovahzul (Skyrim) — see our entry, another fictional fantasy runic.
- Iokharic — see our entry, D&D dragon alphabet.
What are the weaknesses?
- Monoalphabetic substitution — frequency analysis is immediate.
- Public table — available on Tolkien Gateway and dCode.
- No digits — to encode a number, write it out in words.
