 **Summary**:​ This thesis investigates the role of the lips in the perception and production of /r/ in English. Articulatory variation is well-documented in approximant realisations of /r/ in rhotic varieties of English, which present a diverse array of tongue shapes. However, the production of /r/ remains enigmatic, especially concerning non-rhotic Englishes and the contribution of the accompanying labial gesture. The lips are particularly pertinent in the English spoken in England, Anglo-English,​ in which non-lingual labial articulations of /r/ are rapidly gaining currency. I argue that the lips enhance the perceptual saliency of /r/ in both the auditory and the visual domains. I propose that Anglo-English /r/ has developed a specific lip posture, which I relate to increased exposure to non-lingual variants of /r/ and to the pressure to maintain a perceptual contrast with /w/. Perception data reveal that visual cues of the lips are more prominent than the auditory ones for the /r/-/w/ contrast in Anglo-English and that seeing the speaker’s lips may even override the auditory perception of the contrast. This thesis has theoretical implications for the nature of speech perception in general, as well as for the role of visual speech cues in diachronic sound change. **Summary**:​ This thesis investigates the role of the lips in the perception and production of /r/ in English.
