Wuxia (武俠 lit. martial heroes) is a genre of Chinese historical fiction focusing on stories of martial artists and warriors in ancient Chinese settings. Wuxia works, while historically comprised mostly of literature, have grown to include Chinese opera, films, television series, manhua (comics), and video games. The genre boasts great popularity in Chinese-speaking areas around the world and is considered a prominent aspect of Asian popular culture.

Wuxia stories follow a hero of some kind, typically of a lower social class, as they fight evil and injustice. The heroes in wuxia works usually follow a form of chivalric, martial code, which differs between the storyteller and era the story is told in and acts similarly to Japanese samurais' bushido , and often belong to a secret warrior society related to the jianghu (rivers and lakes, or the greater world of outlaw martial artists) .

Many ancient Chinese stories feature warriors that would fit this aesthetic today such as the ancient Chinese ballad of Hua Mulan that is dated back to 4th to 6th century CE. Chinese films and plays often followed suit with these legends, and the Wuxia fad arrived in the US with Chinese ethnic enclaves. With Bruce Lee, a Chinese-American martial artist, the aesthetic was popularized among American youth.

The aesthetic is mainly focused on the fandom and general genre of films, books, and folklore that tell of Chinese warriors or martial artists fighting for what is right, usually in an ancient Chinese setting. Anyone who has an appreciation for the genre could be considered a part of the aesthetic, although actual martial artists are considered to be 'figures' of the aesthetic. The heroes in Wuxia work are usually similar in some ways to each other: they could be both in a low social class and follow a specific moral code as each other, for example.

Many Chinese novel websites, such as Qidian, have their own distinct visual styles for wuxia book covers that often include white backgrounds and Chinese characters.
