Open o or turned c (majuscule: Ɔ, minuscule: ɔ) is a letter of the extended Latin alphabet. In the International Phonetic Alphabet, it represents the open-mid back rounded vowel. It is used in the orthographies of many African languages using the African reference alphabet.

The Yucatec Maya language used Ɔ to transcribe the alveolar ejective affricate {{IPA|[t͡sʼ]}} consonant in the orthography of the Colonial period. Now dz or tsʼ is preferred. {{cite web|url=http://research.famsi.org/whos_who/orthography.htm|title=Who's who in the Classic Maya world: Orthography used in the Who's Who|last=Mathews |first=Peter|website=Foundation for the Advancement of Mesoamerican Studies, Inc.|publisher=Los Angeles County Museum of Art|access-date=June 19, 2024}}

Open o looks like a reversed letter 'C'. Claudius introduced a Ɔ (the antisigma) with the intention of replacing bs and ps.

The Scandinavian explanatory symbol (forklaringstegnet) can be typeset using the open o followed by a colon, thus: ɔ:. It is used to mean "namely", "id est", "scilicet" or similar.{{cite web
