The Cirth (Sindarin pronunciation: [ˈkirθ], meaning "runes"; sg. certh [ˈkɛrθ]) is a semi‑artificial script, based on real‑life runic alphabets, one of several scripts invented by J. R. R. Tolkien for the constructed languages he devised and used in his works. Cirth is written with a capital letter when referring to the writing system; the letters themselves can be called cirth.

In the fictional history of Middle-earth, the original Certhas was created by the Sindar (or Grey Elves) for their language, Sindarin. Its extension and elaboration was known as the Angerthas Daeron, as it was attributed to the Sinda Daeron, despite the fact that it was most probably arranged by the Noldor in order to represent the sounds of other languages like Quenya and Telerin.

Although it was later largely replaced by the Tengwar, the Cirth was nonetheless adopted by the Dwarves to write down both their Khuzdul language (Angerthas Moria) and the languages of Men (Angerthas Erebor). The Cirth was also adapted, in its oldest and simplest form, by various races including Men and even Orcs.
