Jyutping is a romanisation system for Cantonese developed by the Linguistic Society of Hong Kong (LSHK), an academic group, in 1993. Its formal name is the Linguistic Society of Hong Kong Cantonese Romanization Scheme. The LSHK advocates for and promotes the use of this romanisation system.
The name Jyutping (itself the Jyutping romanisation of its Chinese name, 粵拼) is a contraction consisting of the first Chinese characters of the terms Jyut6jyu5 ( 粵語, meaning " Yue language") and ping3jam1 ( 拼音 "phonetic alphabet", also pronounced as " pinyin" in Mandarin).
Despite being intended as a romanisation system to indicate pronunciation, it has also been employed writing Cantonese as an alphabetic language, elevating it from its assistive status to a written language in effect.
The Jyutping system  marks a departure from all previous Cantonese romanisation systems (approximately 12, including Robert Morrison's pioneering work of 1828, and the widely used Standard Romanization, Yale and Sidney Lau systems) by introducing z and c initials and the use of eo and oe in finals, as well as replacing the initial y, used in all previous systems, with j. 
In 2018, the Jyutping system was updated to include the -a and -oet finals, to reflect syllables recognized to be part of Cantonese phonology in 1997 by the Jyutping Work Group of the Linguistic Society of Hong Kong. 
- Only the finals m and ng can be used as standalone nasal syllables.
- ^ ^ ^ Referring to the colloquial pronunciation of these words.
- ^ Used for elided words in casual speech such as a6 in 四十四 (sei3a6sei3), elided from sei3 sap6 sei3. 
- ^ Used for onomatopoeias such as oet6 for belching or goet4 for snoring.
There are nine tones in six distinct tone contours in Cantonese. However, as three of the nine are entering tones ( Chinese: 入聲; Jyutping: jap6sing1), which only appear in syllables ending with p, t, and k, they do not have separate tone numbers in Jyutping (though they do in Cantonese Pinyin; these are shown in parentheses in the table below). A mnemonic which some use to remember this is 「風水到時我哋必發達」or “ Feng Shui [dictates that] we will be lucky.”

Jyutping and the Yale Romanisation of Cantonese represent Cantonese pronunciations with the same letters in:
- The initials: b, p, m, f, d, t, n, l, g, k, ng, h, s, gw, kw, w.
- The vowel: aa (except when used alone), a, e, i, o, u, yu.
- The nasal stop: m, ng.
- The coda: i, u, m, n, ng, p, t, k.
But they differ in the following:
- The vowels eo and oe represent /ɵ/ and /œː/ respectively in Jyutping, whereas the eu represents both vowels in Yale.
- The initial j represents /j/ in Jyutping whereas y is used instead in Yale.
- The initial z represents /ts/ in Jyutping whereas j is used instead in Yale.
- The initial c represents /tsʰ/ in Jyutping whereas ch is used instead in Yale.
- In Jyutping, if no consonant precedes the vowel yu, then the initial j is appended before the vowel. In Yale, the corresponding initial y is never appended before yu under any circumstances.
- Jyutping defines three finals not in Yale: eu /ɛːu/, em /ɛːm/, and ep /ɛːp/. These three finals are used in colloquial Cantonese words, such as deu6 (掉), lem2 (舐), and gep6 (夾).
- To represent tones, only tone numbers are used in Jyutping whereas Yale traditionally uses tone marks together with the letter h (though tone numbers can be used in Yale as well).
Jyutping and Cantonese Pinyin represent Cantonese pronunciations with the same letters in:
- The initials: b, p, m, f, d, t, n, l, g, k, ng, h, s, gw, kw, j, w.
- The vowel: aa, a, e, i, o, u.
- The nasal stop: m, ng.
- The coda: i (except for its use in the coda /y/ in Jyutping; see below), u, m, n, ng, p, t, k.
But they have some differences:
- The vowel oe represents both /ɵ/ and /œː/ in Cantonese Pinyin whereas eo and oe represent /ɵ/ and /œː/ respectively in Jyutping.
- The vowel y represents /y/ in Cantonese Pinyin whereas both yu (used in the nucleus) and i (used in the coda of the final -eoi) are used in Jyutping.
- The initial dz represents /ts/ in Cantonese Pinyin whereas z is used instead in Jyutping.
- The initial ts represents /tsʰ/ in Cantonese Pinyin whereas c is used instead in Jyutping.
- To represent tones, the numbers 1 to 9 are usually used in Cantonese Pinyin, although the use of 1, 3, 6 to replace 7, 8, 9 for the checked tones is acceptable. However, only the numbers 1 to 6 are used in Jyutping.

The Jyutping method allows a user to input Chinese characters by entering the jyutping of a Chinese character (with or without tone, depending on the system) and then presenting the user with a list of possible characters with that pronunciation.
