Dizelaši (Дизелаши) was a youth subculture that became prominent in Serbia, particularly Belgrade, during the turbulent period of the Yugoslav Wars in the 1990s. The name, meaning "Diesel boys," is believed to refer both to the popularity of the Italian brand Diesel and the subculture's stereotypical association with the black market, including the smuggling of fuel during the era's sanctions.

Rooted in working-class youth, the Dizelaši were often linked to petty crime and a tough, macho street culture that developed amidst the social and economic crisis. Their distinctive fashion style was a key identifier, characterized by flashy tracksuits with the trousers tucked into socks, bomber jackets, athletic sneakers (notably Nike Air Max), shaved heads, and visible status symbols like thick gold chains. The subculture is also strongly associated with the popular music genres of the time, especially turbo-folk and Eurodance.

The Dizelaši subculture gained prominence in Serbia during the 1990s, an era defined by the Yugoslav Wars and severe international sanctions. The style was popularized by cultural touchstones of the time, including the infamous gangster Aleksandar "Knele" Knežević and the influential 1998 film Rane (The Wounds), whose characters were widely emulated by rebellious youth. The economic hardship of the sanctions made Western brands nearly impossible to obtain legally, turning them into highly wanted status symbols. This context fueled the subculture's connection to the black market and petty crime, as it was often the only way to acquire the desired clothing and accessories, though many youths simply adopted the aesthetic without engaging in criminal activity.

In recent years, a nostalgic revival known as " Neo-Dizelaši " has emerged, reinterpreting the 1990s style with modern elements like tapered tracksuits and different sneaker models. This subculture is also considered a direct predecessor to the more recent Balkan youth subculture known as Gaserji .

The Dizelaši fashion of the 1990s was a mix of casual sportswear and conspicuous status symbols. The quintessential uniform was a colorful tracksuit, often from brands like Kappa or Reebok, with the trouser legs characteristically tucked into the socks. This was frequently paired with athletic sneakers, particularly Nike Air Max models. Other common garments included baggy Diesel jeans and bomber jackets. The look was defined by its accessories, most importantly the display of bold, often fake, gold jewelry, such as thick chains and bracelets, which served as a primary indicator of wealth and street credibility in a period of economic hardship.

The attitude of the Dizelaši subculture was shaped by the social and economic turmoil of 1990s Serbia. It is characterized by a tough, macho demeanor, a glorification of the criminal lifestyle as a path to wealth, and a strong sense of Serbian nationalism. This mindset was reflected in their cultural tastes, particularly their devotion to Turbo-folk music, a genre whose lyrics often celebrate materialism, fast living, and nationalist themes that resonated with the subculture's aspirations. Their worldview often manifested in hostility towards other youth subcultures like Punks or Rockers , who were perceived as representing the Western influences that were politically and culturally opposed to their own.
