Ḍ (minuscule: ḍ) is a letter of the Latin alphabet, formed from D with the addition of a dot diacritic.

In the transcription of Afro-Asiatic languages such as Arabic, ⟨ḍ⟩ represents an "emphatic" consonant [dˤ], and is used for that purpose in the Berber Latin alphabet and represents a voiced linguodental oclusive consonant.

In the transcription of Indic and East Iranian languages, and in the orthography of the O'odham and Sicilian languages, ⟨ḍ⟩ represents a retroflex [ɖ]. This was used in a former transcription of Javanese, but has been replaced by ⟨dh⟩.
