Late Registration is the second studio album by the American rapper Kanye West. It was released on August 30, 2005, through Roc-A-Fella Records and Def Jam Recordings. West recorded the album over the course of a year during sessions held at studios in Hollywood and New York City, in collaboration with Jon Brion. The album features guest appearances from Adam Levine, Jamie Foxx, Common, Brandy, Jay-Z, and Nas, among others.

West's production for Late Registration departed from the sped-up soul samples of his debut studio album, The College Dropout (2004), moving towards a more elaborate and orchestral style with a 20-piece ensemble. Drawing creative inspiration from alternative acts such as Fiona Apple and Portishead, he experimented with musical shifts, string arrangements, and a variety of instruments not usually associated with hip hop, including a celesta, harpsichord, and Chinese bells. In an effort to write authentic yet relatable lyrics, West engages in storytelling while showcasing his Christian heritage that informed his relationship to the capitalist market economy. He critiques multiple issues, such as institutional racism, higher education, health care, and the blood diamond trade.

A widespread critical success, Late Registration has often been viewed as a progression from The College Dropout and a pivotal release in hip hop. Numerous reviewers praised the former's elegant and ambitious musical direction, while some highlighted West's songwriting and performances for their balance of pop and conscious hip hop sensibilities. It was named to year-end lists for 2005 by multiple publications, such as Rolling Stone, Time, and USA Today. The album led to West receiving eight nominations at the 48th Annual Grammy Awards, including Album of the Year and Best Rap Album, winning the latter.

Surpassing The College Dropout's commercial success, Late Registration debuted at number one on the US Billboard 200 and sold 860,000 copies in the first week, while reaching the top 10 in nine other countries, including the United Kingdom and Ireland. It eventually sold more than 3,000,000 copies in the US and received a five-times platinum certification from the Recording Industry Association of America (RIAA), as well as sales certifications in several other territories. Five accompanying singles were released, including the hits "Touch the Sky", "Heard 'Em Say", and "Gold Digger", the latter of which topped the Billboard Hot 100. Music videos for all five singles were produced, while West also promoted the album with the Touch the Sky Tour (2005–06) and his debut live album, Late Orchestration (2006). Since then, Late Registration has frequently appeared on top albums lists, including Rolling Stone's "500 Greatest Albums of All Time", on which it ranked 117th in 2020.
