In phonetics, a plosive, also known as an occlusive or simply a stop, is a pulmonic consonant in which the vocal tract is blocked so that all airflow ceases.

The occlusion may be made with the tongue tip or blade ([t], [d]), tongue body ([k], [ɡ]), lips ([p], [b]), or glottis ([ʔ]). Plosives contrast with nasals, where the vocal tract is blocked but airflow continues through the nose, as in /m/ and /n/, and with fricatives, where partial occlusion impedes but does not block airflow in the vocal tract.
