Eth (//, uppercase: Ð, lowercase: ð; also spelled edh or eð) is a letter used in Old English, Middle English, Icelandic, Faroese (in which it is called edd), and Elfdalian. It was also used in Scandinavia during the Middle Ages, but was subsequently replaced with dh and later d. It is transliterated to d (and d- is rarely used as a mnemonic). Its use has survived in Iceland and the Faroe Islands. The capital eth resembles a D with a line through the vertical stroke. The lower case resembles reversed 6 with a line through the top. The lower-case letter has been adopted to represent a voiced dental fricative in the International Phonetic Alphabet.
In Icelandic, ð represents a (usually apical) voiced alveolar non-sibilant fricative [ð̠], similar to the th in English "the", but it never appears as the first letter of a word, where þ is used in its place. The name of the letter is pronounced [ɛθ̠]; i.e., voiceless, unless followed by a vowel.
In Faroese, ð is not assigned to any particular phoneme and appears mostly for etymological reasons; however, it does show where most of the Faroese glides are, and when the ð is before r it is, in a few words, pronounced [ɡ]. In the Icelandic and Faroese alphabets, ð follows d.
In Old English, ð (referred to as ðæt by the Anglo-Saxons) was used interchangeably with þ (thorn) to represent either voiced or voiceless dental fricatives. The letter ð was used throughout the Anglo-Saxon era, but gradually fell out of use in Middle English, practically disappearing altogether by 1300; þ survived longer, ultimately being replaced by the modern digraph th.
Lower-case eth is used as a symbol in the International Phonetic Alphabet (IPA), again for a voiced dental fricative, and in IPA usage, the name of the symbol is pronounced with the same voiced sound, as /ɛð/. (The IPA symbol for the voiceless dental fricative is θ.)

- The letter ð is sometimes used in mathematics and engineering textbooks as a symbol for a spin-weighted partial derivative. This operator gives rise to spin-weighted spherical harmonics.
- The modern Greek letter delta (Δ, δ) has, in general, the same phonetic value, and ð is the only Latin alphabet letter faithfully representing delta's phonetic value. (In Ancient Greek, delta represented a d sound.)
- Icelandic words cannot start with ð (sometimes used as a "play" on English such as the Icelandic band Ðe lónlí blú bojs i.e. The lonely blue boys).
