The Linguistic Society of Hong Kong Cantonese Romanization Scheme, also known as Jyutping, is a romanisation system for Cantonese developed in 1993 by the Linguistic Society of Hong Kong (LSHK).

The name Jyutping (itself the Jyutping romanisation of its Chinese name, 粵拼) is a contraction of the official name, and it consists of the first Chinese characters of the terms jyut6 jyu5 (Chinese: 粵語; lit. 'Cantonese language') and ping3 jam1 (Chinese: 拼音; lit. 'phonetic alphabet'; pronounced pīnyīn in Mandarin).

Despite being intended as a system to indicate pronunciation, it has also been employed in writing Cantonese as an alphabetic language [zh]—in effect, elevating Jyutping from its assistive status to a written language.

The Jyutping system departs 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, it was updated to include the -a and -oet finals, to reflect syllables recognized as part of Cantonese phonology in 1997 by the Jyutping Work Group of the Linguistic Society of Hong Kong.

There are nine tones in six distinct tone contours in Cantonese. However, as three of the nine are entering tones (入聲; jap6 sing1), which only appear in syllables ending with p, t, and k, they do not have separate tone numbers in Jyutping (though they do in the ILE romanization of Cantonese; 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; fung1 seoi2 dou3 si4 ngo5 dei6 bit1 faat3 daat6 or "Feng Shui [dictates that] we will be lucky."

Jyutping and the Yale romanisation of Cantonese represent Cantonese pronunciations with the same letters in:

But they differ in the following:
