NPO 3FM is a Dutch public radio station based in Hilversum, North Holland. Launched in 1965 as Hilversum 3, it has evolved into one of the Netherlands' most popular youth-oriented radio channels. The station primarily targets listeners aged 15-35, offering a diverse mix of rock, alternative, indie, pop, and dance music.

Throughout its history, NPO 3FM has undergone several name changes and format adjustments to stay relevant. In 1985, it became Radio 3, and later Radio 3FM in 1994. Since 2003, it has been known simply as 3FM, with the official name changing to NPO 3FM in 2014.

The station is known for its commitment to new and upcoming artists, as well as its annual Serious Request charity event. This initiative, running since 2004, involves DJs broadcasting from a glass house to raise money for humanitarian causes.

NPO 3FM's programming includes a mix of music shows, news updates, and interactive segments. It maintains a strong online presence, offering live streaming and on-demand content through its website and mobile apps. The station continues to play a significant role in shaping Dutch popular music culture and supporting emerging talent.
