Rococopunk is an aesthetic and niche costuming community that combines the opulent fashions of the 18th-century Rococo period with the rebellious attitude and styles of punk . The aesthetic gained visibility in the early 2010s within online communities, often positioned as a more humorous and colorful alternative to Steampunk . It is characterized by handmade outfits that celebrate decadence and excess, blending historical silhouettes with punk modifications.

Rococopunk emerged from costuming groups in the early 2010s, presented as a reaction to the perceived commercialization and seriousness of the Steampunk subculture. The aesthetic is not intended to be historically accurate but rather serves as a playful reinterpretation of history. Adherents of the style emphasize a sense of humor about their costumes and the subculture itself. Participants have described themselves with the portmanteau "classholes," a term meant to capture the fusion of aristocratic Rococo visuals with a defiant punk demeanor. The core philosophy celebrates decadence and excess, deliberately contrasting with the more industrial and subdued color palettes often associated with Steampunk.

The visual style of Rococopunk is a literal fusion of Rococo and punk elements. The clothing, which is typically handmade by its wearers, draws from the late Baroque period, incorporating frilly garments, elaborate silhouettes, and colorful fabrics. These historical components are then combined with punk fashion staples, such as mohawks and other anti-authoritarian stylistic choices.

While the costuming movement is distinct, parallels can be drawn to the work of fashion designer Vivienne Westwood, who frequently blended 18th-century aesthetics with punk stylings. The performer Prince Poppycock, known from his appearance on The X Factor , has also presented a visual style that aligns with the Rococopunk aesthetic. The aesthetic has also been the subject of dedicated art projects, such as The RococoPunk Project by Fifth Wall Media, which created a large-scale "digital baroque painting" featuring numerous subjects in the style.
