Ka with hook (Ӄ ӄ; italics: Ӄ ӄ) is a letter of the Cyrillic script. It is formed from the Cyrillic letter Ka (К к) by the addition of a hook.
Ka with hook is widely used in the alphabets of Siberia and the Russian Far East: Chukchi, Koryak, Alyutor, Itelmen, Yukaghir, Yupik, Aleut, Nivkh and Selkup languages, where it represents the voiceless uvular plosive /q/. It has been sometimes used in the Khanty language as a subtitute for Cyrillic letter Ka with descender, Қ қ, which also stands for /q/.
