Abkhazian Che (Ҽ ҽ; italics: Ҽ ҽ) is a letter of the Cyrillic script.

Abkhazian Che is used in the alphabet of the Abkhaz language, where it represents the voiceless retroflex affricate /ʈʂ/. In the alphabet, it is placed between ⟨Ҷ⟩ and ⟨Ҿ⟩.

The letter only coincidentally resembles a lowercase Latin letter e. Historically, it is the cursive form of the corresponding letter ( ) in the Abkhazian Latin alphabet, where it somewhat resembled a Greek φ.

Cche or Double Che (Ꚇ ꚇ; italics: Ꚇ ꚇ) is a letter of the Cyrillic script. It was used in the old Abkhaz alphabets, where it represents the voiceless retroflex affricate /ʈ͡ʂ/. The letter was invented by baron Peter von Uslar. In 1862 he published his linguistic study "Абхазский язык". The letter is Ҽ-shaped but in 1887 Uslar's study was reprinted by M. Zavadskiy who changed its shape and the result resembled a Cyrillic Ч doubled. Later the letter returned to its initial form which, created by linguist Uslar, is part of the modern Abkhaz alphabet, which is depicted as Ҽ.
