Ċ (minuscule: ċ) is a letter of the Latin alphabet, formed from C with the addition of a dot. It is used in Maltese to represent a voiceless postalveolar affricate, equivalent to English ch ([t͡ʃ]).
It is used in modern transcripts of Old English for the same reason, to distinguish it from c pronounced as [k], which otherwise is spelled the same. Its voiced equivalent is Ġ.
Ċ was formerly used in Irish to represent the lenited form of C. The digraph ch, which is older than ċ in this function in Irish, is now used.
Ċ is also used in the Latin version of Chechen language and Karmeli language as of 1992. The Cyrillic equivalent is ЦӀ, represent the sound [tsʼ].
