M̃ ( majuscule: M̃, minuscule: m̃) is a Latin M with a diacritical tilde.

Linguistic use

M̃–m̃ is or was used as a grapheme in several languages:

• in some languages of Vanuatu, such as North Efate, South Efate and Namakura, it represents a labial-velar nasal [ ŋm]. The letter was introduced by missionaries and has been in use for over a hundred years. (Other Vanuatu languages use an M-macron (m̄) instead.)
• in the Yanesha' language of Peru, m̃ represents a palatalized m
• in Lithuanian, m̃ appears as part of diphthongs
• in the transliteration of the Lycian script, it represents a syllabic m.

In Italian, the abbreviation Ssm̃o or SSm̃o may be used for Santissimo, "most holy" (similarly Latin Ssm̃us for Sanctissimus).
