Dž (titlecase form; all-capitals form DŽ, lowercase dž) is the seventh letter of the Gaj's Latin alphabet for Serbo-Croatian (Bosnian, Croatian, Montenegrin and Serbian), after D and before Đ. It is pronounced [d͡ʒ]. Dž is a digraph that corresponds to the letter Dzhe (Џ/џ) of the Serbian Cyrillic alphabet. It is also the tenth letter of the Slovak alphabet. Although several other languages (see below) also use the letter combination DŽ, they treat it as a pair of the letters D and Ž, not as a single distinct letter.

Note that when the letter is the initial of a capitalised word (like Džungla or Džemper, or personal names like Džemal or Džamonja), the ž is not uppercase. Only when the whole word is written in uppercase, is the Ž capitalised.

In Gaj's Latin alphabet (used for Serbo-Croatian), when the text is written vertically rather than horizontally (on signs, for instance), dž is written horizontally as a single letter; in particular, dž occupies a single square in crossword puzzles. Also, in cases where words are written with a space between each letter, dž is written together without a space between d and ž. These characteristics are also shared by Lj and Nj. Similarly, when a name beginning with Dž is reduced to initial, the entire letter is initial, not just D. For example, Dženan Ljubović becomes Dž. Lj. and not D. L. This behaviour is not the case in Slovak, where it is split into D/d and Ž/ž.

Czech does have the sound d͡ʒ, but in native Czech words it only occurs as a replacement of [t͡ʃ] before other voiced consonants. Therefore, [t͡ʃ] and [d͡ʒ] are written in native words using the same letter č. This is not possible in loanwords, and Czech adopted the Dž orthography in this case (for example džus). In this case, the two letters are always split when text is written vertically. Lithuanian and Latvian similarly use Dž without considering it a separate letter.

Letter "Dž" is found in Unicode at code points U+01C4 (uppercase, DŽ), U+01C5 (titlecase, Dž), and U+01C6 (lowercase, dž). Unicode representations of the letter are very rarely used in digital media, which tends to favor the corresponding two-character combinations. Manufacturers of computer keyboards and typewriters for Croatian users typically do not provide a single key for the letter. X keyboard extension provides latinunicode keyboard layouts for entering Unicode representation of the letter on standard Croatian keyboard.^[1]
