The bilabial ejective is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨pʼ⟩.

Features of the bilabial ejective:

• Its manner of articulation is occlusive, which means it is produced by obstructing airflow in the vocal tract. Since the consonant is also oral, with no nasal outlet, the airflow is blocked entirely, and the consonant is a plosive.
• Its place of articulation is bilabial, which means it is articulated with both lips.
• It is an oral consonant, which means that air is exclusively allowed to escape through the mouth.
• Because the sound is not produced with airflow over the tongue, the central–lateral dichotomy does not apply.
• The airstream mechanism is ejective (glottalic egressive), which means the air is forced out by pumping the glottis upward.

In addition to the languages listed below, this sound is also a common phonological feature of the Ethiopian linguistic area, especially Ethiopian Semitic languages.
