"Rhythm Nation" is a song by American singer Janet Jackson, released as the second single from her fourth studio album Janet Jackson's Rhythm Nation 1814 (1989). It was written and produced by Jackson, in collaboration with James "Jimmy Jam" Harris III and Terrence "Terry" Lewis. Jackson developed the song's concept in response to various tragedies in the media, deciding to pursue a socially conscious theme by using a political standpoint within upbeat dance music. In the United States, it peaked at number two on the Billboard Hot 100 and topped the Hot R&B/Hip-Hop Songs and Dance Club Songs singles charts. It also peak within the top 40 of most singles charts worldwide.

The music video for "Rhythm Nation" was directed by Dominic Sena, serving as the final inclusion in Jackson's long-form Rhythm Nation 1814 film. It portrays rapid choreography within a "post-apocalyptic" warehouse setting, with Jackson and her dancers adorned in unisex military attire. It was filmed in black-and-white to portray the song's theme of racial harmony. Jackson's record label attempted to persuade her against filming the video, but upon her insistence it became "the most far-reaching single project the company has ever attempted." The video received two MTV Video Music Awards for "Best Choreography" and "Best Dance Video." Jackson also won a Billboard Award for "Best Female Video Artist" in addition to the "Director's Award" and "Music Video Award for Artistic Achievement." The Rhythm Nation 1814 film won a Grammy Award for Best Long Form Music Video. The video's outfit was inducted into the National Museum of Women in the Arts and Rock & Roll Hall of Fame, where its hand-written lyrics are also used in the museum's class on female songwriters.
