The voiceless retroflex plosive or stop is a type of consonantal sound, used in some spoken languages.

This consonant is found as a phoneme mostly (though not exclusively) in two areas: South Asia and Australia.

The symbol that represents this sound in the International Phonetic Alphabet is ⟨ʈ ⟩.

Like all the retroflex consonants, the IPA symbol is formed by adding a rightward-pointing hook extending from the bottom of "t" (the letter used for the equivalent alveolar consonant).

Shaded areas denote articulations judged impossible.
