Shin Ramyun/Sin Ramyeon is a brand of instant noodle (including cup ramyeon) that has been produced by the South Korean food company Nongsim since 1 October 1986. The Nongshim R&D team came up with the idea of Sogogijanguk, a cabbage and beef stew, which is one of the most popular traditional South Korean dishes.

After Shin Ramyun was introduced in 1986, Nongshim’s market share 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.

It is now exported to over 100 countries, and is the highest selling instant noodle brand in South Korea. As of 2015, accumulated sold units of Shin Ramyun in the world reached 28 billion units and nearly 27 million US dollar in sales in 2018.

Shin Ramyun, well known for its spicy flavor, is produced in two varieties: the original Shin Ramyun and Shin Ramyun Black,  which was introduced in 2011. 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 stock soup, which gives the soup a more intensely savory flavor.

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