NewJeans Code in Busan (Korean: 뉴진스 코드) is a South Korean travel reality television series produced by Busan Metropolitan City and the Busan Tourism Organization and distributed by SBS. Starring K-pop girl group NewJeans, the three-episode series follows the group as they visit several of Busan's landmarks over the course of a two-day trip. It was created as part of a series of Hallyu content produced to support Busan's bid to host the Expo 2030.

The project was first announced in September 2022 and premiered on SBS TV on October 16, 2022, at 12:10 (KST). Set to be aired for three consecutive Sundays, the final episode was postponed to November 6, 2022. The series was released for streaming on Wavve, where it recorded 23.8 million hours of viewing in two months. After the broadcast, several filming locations were crowded with fans, which led the Busan Tourism Organization to create two travel guides based on the series.
