Romanization of Korean

The romanization of Korean (Korean: 로마자 표기법; RR: romaja pyogibeop) is the use of the Latin script to transcribe the Korean language.

There are multiple romanization systems in common use. The two most prominent systems are McCune–Reischauer (MR) and Revised Romanization (RR). MR is almost universally used in academic Korean studies, and a variant of it has been the official system of North Korea since 1992. RR is the official system of South Korea, and has been in use since 2000.

The earliest romanization systems for Korean emerged around the mid-19th century. Due to a number of factors, including the properties of the Korean language and alphabet, as well as social and geopolitical issues, a single settled standard did not emerge. By 1934, there were 27 extant romanization systems, and by 1997 there were over 40.
