A voiceless postalveolar fricative is a type of consonantal sound used in many spoken languages. It is familiar to English-speakers as the "sh" sound in "ship".

The International Phonetic Association uses the phrase voiceless postalveolar fricative for the sibilant sound [ ʃ ], though technically it also describes the voiceless postalveolar non-sibilant fricative [ɹ̠̊˔], for which there are significant perceptual differences.
