Three alphabets are used to write Kazakh: the Cyrillic, Latin and Arabic scripts. The Cyrillic script is used in Kazakhstan, Russia, and Mongolia. An October 2017 Presidential Decree in Kazakhstan ordered that the transition from Cyrillic to a Latin script be completed by 2031. The Arabic script is used in Saudi Arabia, Iran, Afghanistan, and parts of China.

The Kazakh Cyrillic alphabet is used in Kazakhstan, the Altai Republic in Russia, and the Bayan-Ölgiy Province in Mongolia. It is also used by Kazakh populations in Kyrgyzstan, Russia, Turkmenistan and Uzbekistan, as well as diasporas in other countries of the former USSR. It was introduced during the Russian Empire period in the 1800s, and then adapted by the Soviet Union in 1940.

In the nineteenth century, Ibrahim Altynsarin, a prominent Kazakh educator, first introduced a Cyrillic alphabet for transcribing Kazakh. Russian missionary activity, as well as Russian-sponsored schools, further encouraged the use of Cyrillic in the nineteenth and early twentieth centuries. The alphabet was reworked by Sarsen Amanzholov and accepted in its current form in 1940. It contains 42 letters: 33 from the Russian alphabet with 9 additional letters for sounds of the Kazakh language: Ә, Ғ, Қ, Ң, Ө, Ұ, Ү, Һ, І (until 1951 Ӯ was used instead of Ұ). Initially, Kazakh letters came after letters from the Russian alphabet, but now they are placed after Russian letters similar in sound or shape.

The letters В, Ё (since 1957), Ф, Ц, Ч, Ъ, Ь and Э are not used in native Kazakh words. Of these, Ё, Ц, Ч, Ъ, Ь, Э, are used only in words borrowed from Russian or through the Russian language which are written according to Russian orthographic rules. The letter E in Kazakh makes a sound similar to Э in Russian (ex. Kazakh: Екібастуз - Russian: Экибастуз). The letter Ж is pronounced similarly to ДЖ in Russian (approximately like J in English). The letter Х is pronounced like a wheezing h (hard h). The letter Һ is frequently used in Arabic-Persian borrowings and is often pronounced like an unvoiced Х (as /h/, soft h, or a voiceless glottal fricative). In rapid conversation, the letter Қ (Q) can be pronounced like X (if Қ is in the middle of a word and before a consonant) or like Ғ. The letter Щ is used for the long Ш sound in three native words (ащы 'bitter', тұщы 'saltless', кеще 'stupid') and their derivatives, as well as in loanwords.

The letter И represents the tense vowel [i] obtained from the combinations ЫЙ /əj/ and ІЙ /ɪj/. The letter У represents /w/ and the tense vowel [u] obtained from the combinations ҰУ /ʊw/, ҮУ /ʉw/, ЫУ /əw/ and ІУ /ɪw/. Additionally, И and У are retained in words borrowed from Russian, where they represent the simple vowels [i] and [u] respectively.
