This article includes an overview of the major events and trends in popular music in the 2000s.

In North America, Europe and Oceania, pop and dance music subgenres, such as dance-pop, teen pop and bubblegum pop, have remained popular throughout or in parts of the decade. Similarly to the 1990s, hip hop and contemporary R&B also remained highly popular genres throughout the decade. Unlike many past decades, the 2000s did not see the creation of as many new styles, with the exception of a few indie-related genres such as emo rock. The pitch correction tool Auto-Tune has been described as the most distinguishable element of music in the 2000s. Despite the hip hop dominance which lasted for the decade, rock music was still popular, notably alternative rock, and especially genres such as post-grunge, nu metal, pop punk, emo, post-hardcore, metalcore and indie rock; the decade also saw the garage rock and post punk revival. Despite a slight slip of popularity in the early part of the decade, adult contemporary and country music were still able to find success throughout the 2000s. Electronic music was also highly popular throughout the decade; at the beginning of the 2000s, genres such as trance, chillout, house, indietronica, and Eurodance (in Europe) were popular, yet, by the latter end of the decade, dance-oriented forms of electronic music, such as synthpop, electropop, nu-disco and electro house had become popular. By the end of the decade, a fusion between hip hop and electronic dance which had originated in the 1980s, known as also grew successful. In general, pop became more commercially successful than all other forms of popular music by the late 2000s due to recession.
