Neo-psychedelia is a diverse genre of psychedelic music that draws inspiration from the sounds of 1960s psychedelia, either updating or copying the approaches from that era. It initially flourished as an international movement of artists who applied the spirit of psychedelic rock to new styles. It has occasionally seen mainstream pop success but is typically explored within the alternative rock scene.

Neo-psychedelia developed in the late-1970s as an outgrowth of the British post-punk scene, where it was also known as acid punk. Prince explored neo-psychedelic elements in his successful mid-1980s work. A neo-psychedelic wave of British alternative rock in the 1980s spawned the subgenres of dream pop and shoegazing. Neo-psychedelia may also include forays into psychedelic pop, jangly guitar rock, heavily distorted free-form jams, or recording experiments.
