Gangnam Style is a K-pop single by South Korean musician PSY. The song was released on July 15, 2012, as the lead single of his sixth studio album PSY 6 (Six Rules), Part 1. "Gangnam Style" debuted at number one on the Gaon Chart, the national record chart of South Korea. As of December 18, 2012, the music video has been viewed over 971 million times on YouTube, and is the site's most watched video after surpassing Justin Bieber's single "Baby".

The phrase "Gangnam Style" is a Korean neologism that refers to a lifestyle associated with the Gangnam District of Seoul.
