Shin Ramyun (Korean: 신라면; Hanja: 辛라면) is a brand of instant noodle (including cup ramyeon) that has been produced by the South Korean food company Nongshim since October 1, 1986. It is now exported to over 100 countries, and is the best-selling instant noodle brand in South Korea.

Shin Ramyun, well known for its spicy flavor, is produced in at least four varieties: the original Shin Ramyun and Shin Ramyun Black, which was introduced in 2011 as well as Super Spicy, which was released in 2019, and a shrimp flavor that is only available in China and Singapore. A standard package of Shin Ramyun consists of noodles, a packet of flavoring powder (soup base), and a packet of vegetable flakes. Shin Ramyun Black contains an extra packet of beef soup stock, which gives the soup a more intensely savory flavor. Additionally, an extra-spicy variant, Shin Red, was introduced in 2020.

Shin Ramyun was introduced in October 1986 by Nongshim. The Nongshim R&D team was inspired by sogogi jangguk, a popular Korean spicy cabbage and beef stew.

After Shin Ramyun was introduced, Nongshim's share of the instant noodle market hit 46.3% in 1987, and exceeded 50% for the first time in 1988 (53.8%). With the market share of over 20% just by itself, Shin Ramyun is a leading brand of the instant noodles in Korea.

In 2007, Nongshim launched a kimchi-flavoured version of Shin Ramyun.

In August 2014, Nongshim revised its recipe for noodle blocks across its line for a chewier consistency, along with a revamped external packaging.

In 2015, Shin Ramyun achieved 28 billion units sold since it was first introduced. Shin Ramyun is listed on the National Brand Consumption Index (NBCI) as the number 1 brand in South Korea (2012–2016) for its brand awareness and brand power.

In 2019, Nongshim launched a non-fried version of its packet noodle which has almost half a reduction on calories.
