Eth is a letter used in Old English, Middle English, Icelandic and Elfdalian. It was used in Scandinavia during the Middle Ages but was subsequently replaced with dh and d, it is transliterated as d. The lowercase version has been adopted to represent a voiced dental fricative in the International Phonetic Alphabet. In Old English, ð was used interchangeably with þ to represent the Old English dental fricative phoneme /θ/ or its allophone /ð/, which exist in modern English phonology as the voiced and voiceless dental fricatives now spelled "th". Unlike the runic letter þ, ð is a modified Roman letter. Ð was not found in the earliest records of Old English. A study of Mercian royal diplomas found that ð began to emerge in the early 8th century, with ð becoming preferred by the 780s. Another source indicates that the letter is "derived from Irish writing"; the lowercase version has retained the curved shape of a medieval scribe's d, which d itself in general has not. Ð was used throughout the Anglo-Saxon era but fell out of use in Middle English disappearing altogether by 1300.

In Icelandic, ð represents a voiced dental fricative, the same as the th in English that, but it never appears as the first letter of a word, where þ is used in its stead. The name of the letter is pronounced in isolation as and therefore with a voiceless rather than voiced fricative. In Faroese, ð is not assigned to any particular phoneme and appears for etymological reasons. In the Icelandic and Faroese alphabets, ð follows d. In Olav Jakobsen Høyem's version of Nynorsk based on Trøndersk, ð was always silent and was introduced for etymological reasons. Ð has been used by some in written Welsh to represent /ð/, represented as dd. U+1D9E ᶞ MODIFIER LETTER SMALL ETH is used in phonetic transcription. U+1D06 ᴆ LATIN LETTER SMALL CAPITAL ETH is used in the Uralic Phonetic Alphabet; the Faroese and Icelandic keyboard layouts have a dedicated button for eth. On Microsoft Windows, eth can be typed using the alt code Alt+ for lowercase or Alt+ for uppercase, or by typing AltGr+d using the US International keyboard layout.

On macOS, eth can be typed by activating the ABC Extended keyboard layout and typing ⌥ Option+D. Using the compose key, popular on Linux, eth can be typed by typing Compose D H for lowercase or Compose ⇧ Shift+D ⇧ Shift+H for capital letters. On Chrome OS, holding Alt Gr and pressing the D key will result in ð being written. Holding shift or putting Caps Lock on will result in Ð. For text-messaging the letter Ð is available on a standard Icelandic keyboard, or may be available on the long-press for'D' when the Icelandic keyboard is downloaded if not in use. Substituting the three letters "eth" is an acceptable alternative, or workaround; 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. A capital eth is used as the currency symbol for Dogecoin.
