A voiceless velar affricate is a type of consonantal sound, used in some spoken languages. The symbols in the International Phonetic Alphabet that represents this sound are ⟨k͡x⟩ and ⟨k͜x⟩. The tie bar may be omitted, yielding ⟨kx⟩.

Some languages have a voiceless pre-velar or post-palatal affricate, which is articulated slightly more front compared with the place of articulation of the prototypical voiceless velar affricate, though not as front as the prototypical voiceless palatal affricate – see Voiceless palatal affricate § Post-palatal for more information.

Conversely, some languages have a voiceless post-velar affricate, which is articulated slightly behind the place of articulation of the prototypical voiceless velar affricate, though not as back as the prototypical voiceless uvular affricate – see Voiceless uvular affricate § Pre-uvular for more information.
