The (near-)open front rounded vowel, or (near-)low front rounded vowel, is a type of vowel sound that has not been confirmed to be phonemic in any spoken language. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɶ⟩, a small capital ⟨Œ⟩. ⟨œ⟩, the lowercase of the ligature, is used for the open-mid front rounded vowel.

While the IPA chart lists it as a fully open vowel, the rounded equivalent of [a], Ladefoged characterizes it as near-open, the rounded equivalent of [æ].

A phoneme generally transcribed by this symbol is reported from the Bavarian dialect of Amstetten. However, it is phonetically open-mid, [œ].

It occurs allophonically in Weert Limburgish as well as in some speakers of Danish and Swedish. Certain transcriptions of Danish use ⟨ɶ⟩ to denote an open-mid front rounded vowel [œ].

In Maastrichtian Limburgish, the vowel transcribed with ⟨ɶː⟩ in the Mestreechter Taol dictionary is phonetically near-open central [ɐ̹ː]. It is a phonological open-mid front rounded vowel, the long counterpart of /œ/.

Riad (2014) reports that [ɶː] in Stockholm Swedish is sometimes difficult to distinguish from [ɒː], which is the main realization of the /ɑː/ phoneme, a sign that both vowels are phonetically very close.
