Untuk Huruf E (Е е) dari Alfabet Bulgaria, Makedonia, Serbia dan Ukraina, lihat Ye (Kiril).

**E** (Э э; italik: *Æ æ*; juga dikenal sebagai ***e*** **terbalik**, dari Rusia э оборо́тное, *e oborótnoye*, [ˈɛ ɐbɐˈrotnəjə] adalah huruf yang ditemukan dua Bahasa Slavia: Rusia dan Belarus. Itu melambangkan vokal [e] dan [ɛ], seperti e dalam kata "**e**ditor". Dalam bahasa Slavia lain yang menggunakan Alfabet Kiril, bunyinya diwakili oleh Ye (Е е), yang mewakili bahasa Rusia dan Belarusia 
[je] di posisi awal dan postvokal atau [e] dan konsonan yang terpalatalisasi sebelumnya. Huruf ini sangat mirip dan tidak boleh disamakan dengan huruf Kiril yang lebih tua Ye Ukraina (Є є), di mana Э adalah versi terbalik.

Dalam Alfabet Kiril Moldova, yang digunakan di RSS Moldova selama Uni Soviet dan masih digunakan di Transnistria, hurufnya sesuai dengan [ă] dalam bahasa Rumania latin, dan fonem [ə]. Ini juga digunakan dalam Alfabet Kiril yang digunakan oleh Mongolia dan banyak Uralik, Kaukasia dan Turkik bekas Uni Soviet.

Huruf ⟨э⟩ berasal dari abad ketiga belas sebagai varian dari ⟨є⟩, pada awalnya, menurut Đorđić  dalam posisi akhir baris superskrip, tetapi pada akhir abad ini juga di tempat lain. Pada abad-abad berikutnya ia terus muncul secara sporadis sebagai varian yang tidak biasa dari ⟨є⟩, tetapi paling lambat pada abad ke-15 di antara orang-orang Slavia Timur itu mulai digunakan untuk menunjukkan inisial (tidak teriotasikan) [e]. Menurut Yefim Karskiy, "Ustav Rusia Barat mengetahui ⟨э⟩, misalnya dalam Miscellany of the 15th c. dari Public Library (manuscr. #391) (экъсеквїє dll.), kronik cc ke-15 dan ke-16, Miscellany of Poznań (c. ke-16) dan  Statuta 1588... Sulit untuk mengatakan apakah ini dikembangkan di sini secara mandiri atau berasal dari manuskrip Slavia Selatan, di mana ⟨э⟩ terjadi pada cc ke-13-14." Meskipun revisi tata bahasa Meletius Smotrytsky yang diterbitkan di Moskwa pada tahun 1648 tidak menyertakan ⟨э ⟩ dalam abjadnya, ia secara konsisten menulis Этѷмолѻ́гїа (*Etymologia*), berbeda dengan Єтѷмоло́ґїѧ dalam edisi pertama tahun 1619. Itu sama sekali tidak terbatas pada ini berfungsi dalam periode, bagaimanapun, sebagai ejaan umum реэстръ, маэоръ (di samping маиоръ, маіоръ) untuk bahasa Rusia modern реестр dan майор.

Specimens of the civil script with annotations by Peter I.
In the specimens of the civil script presented to Peter I in 1708, forms of ⟨э⟩ were included among forms of ⟨є⟩, but the latter was deleted by Peter. The former was used in some early 18th-century Russian texts, but some authorities of the period considered it superfluous, like Mikhail Lomonosov, on the grounds that "the letter Е, having several different pronunciations, could serve in the pronoun етотъ and the interjection ей" and that it was inappropriate to introduce letters solely for use in loanwords. However, the inclusion of ⟨Э⟩ in its modern function, in the Russian Academy's Dictionary of 1789–94, marks the point from which it can be considered as an established part of the Russian orthographical standard.

There were still some objections to the letter even as late as 1817, when M. T. Kačenovskij was questioning whether "yet another hard э" was necessary when the language already had "a soft ѣ and a hard е".

In contemporary Russian, ⟨э⟩ is used to represent [e], [ɛ] in initial position (**э**лектричество 'electricity') and postvocalic position (ду**э**ль 'duel'). Among such words are only a few native Russian roots: эт- (это 'this is', этот/эта/это 'this (m./f./n.)', эти 'these', поэтому 'thus' etc.), эк- (экий 'what a'), эдак-/этак- (эдак/этак 'that way', эдакий/этакий 'sort of') and a few interjections like эй 'hey', э 'uh, oh', э-э-э 'uh'. 

Even though Russian contains a significant number of loanwords in which [e] occurs after a hard (unpalatalised) consonant, it is still the practice to use the letter ⟨е⟩ for [e], [ɛ]: теннис, сепсис (tennis, sepsis). There are few traditional exceptions to that practice among common noun loanwords:

* the original list (the first half of the 20th century) contained just three words:
	+ мэр 'mayor', from French 'maire'
	+ пэр 'peer (a noble)', from French 'pair'
	+ сэр 'sir', from English or from Old French 'sieur'
* two later additions (1950s-1960s):
	+ мэтр 'master, skilled artist', from French 'maître'
	+ пленэр, from French '(en) plein air'
* new additions (1980s and later) are more numerous:
	+ рэкет 'racket, racketeering', from English
	+ рэп 'rap (music)', from English
	+ фэнтези 'fantasy (literature)', from English
	+ and several others; spelling of new words sometimes varies and dictionaries often give variants or contradict one another (like хетчбэк 'hatchback (car)' in spelling dictionary vs хетчбек/хэтчбек in explanatory dictionary).

In proper nouns, however, ⟨э⟩ may occur after consonants: Улан-Удэ 'Ulan-Ude' and Блэр 'Blair'. However, many such loanwords are spelled with ⟨е⟩: Блерио 'Blériot' (a French aviator). That is the case especially for names that entered the language centuries ago like: Берлин, 'Berlin'. The use of ⟨э⟩ is much more frequent for names from non-European languages: Мао Цзэдун 'Mao Zedong'.

The letter ⟨э⟩ is also used in Russian to render initial [œ] in foreign words: thus Eure (the river in France) is written Эр. After consonants this is transcribed as ⟨ё⟩. In the 19th century, some writers used ⟨ӭ⟩ for that sound in both positions, but that was never accepted as standard orthography. (The letter ⟨ӭ⟩ was re-invented in the 20th century for Kildin Sami.) It is also used to represent a stressed [æ] in languages such as English, which can cause a problem of conflating [æ] with English [ɛ] (for example, "Addison" and "Edison" would be spelled the same). However, in other positions, Russian also uses ⟨а⟩ for [æ] and ⟨е⟩ for [ɛ].

Unlike Russian, Belarusian has many native words in which it occurs after a hard consonant. Moreover, its orthography was standardized later than that of Russian (which reached its present form at the beginning of the 20th century), on the basis of the spoken language rather than historical tradition. Consequently, ⟨э⟩ and ⟨е⟩ are written in accordance with pronunciation: ⟨э⟩ for initial [e] and after hard consonants, ⟨е⟩ for initial and postvocalic [je] and after soft consonants. That also means that ⟨э⟩ is much more frequent in Belarusian than in Russian.

In Tuvan the Cyrillic letter can be written as a double vowel.

Dalam Bahasa Tajik, huruf е dan э mempunyai fungsi yang sama , kecuali э yang dipakai dalam awal kata (misal. Эрон, "Iran").

In Mongolian, э is the standard letter to represent the /ɛ/ phoneme. It is often written doubled to represent the /eː/ phoneme. Е, however, is only used in the few Mongolian words containing it, Russian loanwords and Russian-style transcriptions of foreign names.
