The Newport music scene, in and around Wales' third city, has been well documented and acclaimed for cultivating bands, singers, and famous music venues. Newport has been traditionally a rock city since the 1970s, but it has evolved over the years to include forms of punk, 1990s alt-rock, and more recently metal and hip-hop.

Newport is a city and county borough in Wales, situated on the River Usk close to its confluence with the Severn Estuary, 12 mi (19 km) northeast of Cardiff. The population grew considerably between the 2011 and the 2021 census, rising from 145,700 to 159,587, the largest growth of any unitary authority in Wales. Newport is the third-largest principal authority with city status in Wales, and sixth most populous overall. Newport became a unitary authority in 1996 and forms part of the Cardiff-Newport metropolitan area, also known as the Cardiff Capital Region.
