| Nasal labial–velar approximant | |

| w̃ |
The nasal labial–velar approximant is a type of consonantal sound used in some languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨w̃⟩, that is, a w with a tilde. The equivalent X-SAMPA symbol is w~.
The nasal approximants [ȷ̃] and [w̃] may also be called nasal glides. In some languages like Portuguese, they form a second element of nasal diphthongs.

Features
Features of the nasal labial–velar approximant:
- Its manner of articulation is approximant, which means it is produced by narrowing the vocal tract at the place of articulation, but not enough to produce a turbulent airstream.
- Its place of articulation is labial–velar, which means it is simultaneously articulated with the lips and with the back part of the tongue (the dorsum) against the soft palate (the velum). The dorsal closure is made and released slightly before the labial closure, but they overlap for most of their duration.
- Its phonation is voiced, which means the vocal cords vibrate during the articulation.
- It is a nasal consonant, which means air is allowed to escape through the nose, either exclusively (nasal stops) or in addition to through the mouth.
- It is a central consonant, which means it is produced by directing the airstream along the center of the tongue, rather than to the sides.
- The airstream mechanism is pulmonic, which means it is articulated by pushing air solely with the intercostal muscles and abdominal muscles, as in most sounds.
