Chun-Li (/tʃʌnˈliː/ ^ⓘ; Japanese: チュンリー, Hepburn: Chun-Rī) is a character in Capcom's Street Fighter video game series. She first appeared in Street Fighter II: The World Warrior in 1991 and is the first female playable character to appear in a fighting game to gain mainstream recognition. She is a martial artist and Interpol officer who seeks revenge for the death of her father by the series' antagonist M. Bison.

Since her debut, Chun-Li has become a pop culture icon, being widely notable beyond the games and among one of the series' most iconic characters. She has appeared in nearly all subsequent installments of the series and several other Capcom games, in addition to third-party games. She is also featured in Street Fighter-related media, including two feature films, multiple anime and comic book productions, and other official series merchandise. She has earned much positive fan and critical reception for factors such as her backstory, athleticism and in-game playability, and she is considered a trailblazer for female characters in fighting titles and general video gaming.

Chun-Li's design was primarily inspired by Tong Pooh, a female villain from Strider, an earlier Capcom game. Capcom designer Akira Nishitani, recounting the creation of the character, said: "Previously there were no women in fighting games. In Chun-Li's case, I wanted a woman in the game. I determined what her fighting abilities would be. Then China just came up as a possible homeland." Capcom artist and designer Akira "Akiman" Yasuda said the initial inspiration for Chun-Li came from the 1983 anime film Harmagedon: Genma Wars (featuring early character design work by Akira creator Katsuhiro Otomo), which had a Chinese female character called Tao. Chun-Li was originally known as just 'Chinese Girl' among the development team. She had a backflip attack that was popular among testers but deemed too strong, and unfortunately had to be cut from the game after they ran out of time. Her name means 'beautiful spring' in Chinese as Chūn (春) means 'the season of spring', and lì (麗) means 'beautiful' in Mandarin dialects.

Yasuda recalled they only had five weeks to make Chun-Li in the game and he was deeply worried about the quality of her design and how she would be received. Chun-Li "was wearing pants right up until the very end [of the development]. When we made the sprites I thought she didn't look right, so I had them changed to tights instead." Akiman added that they "wanted Street Fighter II to be more entertaining than its predecessor. That also helps explain how Chun-Li came to be. Having a female character in the game completely changes the game's dynamic, she brightens up the entire palette. We needed a reason for her to fight, and so an evil empire [of M. Bison] came to mind." He also said: "To be honest, I spent some time worrying about putting Chun-Li, the heroine, into such a plain setting. Ordinarily, you don't see women participating in global martial arts tournaments. Just by adding her we were starting to push things to the 'fun' side. I didn't think about it at the time, but thinking about it now, from the moment we put Chun-Li into the game we were already pushing things towards the full-on entertainment side."

Chun-Li was designed with an exceptionally strong physique because she was the sole woman among a roster of powerful male characters in Street Fighter II. To overcome this perceived imbalance, she was devised as a character who had mastered Chinese kenpo and really pushed her body to the limit so that she could compete with such a cast of large and imposing men. She was nevertheless the fastest but physically weakest character in her first game. Capcom producer Yoshiki Okamoto said he wanted to also make the life bar for Chun-Li "shorter than for the other characters because women are not as strong. But Nishitani didn't want to do that. We both had legitimate reasons, but then we came to an agreement to not make it shorter."

Chun-Li is particularly well known for her very muscular legs, while depictions of the rest of her body are more variable. According to Capcom composer Yoko Shimomura, Chun-Li's big thighs originated from Akiman's personal fetish. The size of Chun-Li's thighs massively increased in Street Fighter III. Capcom producer Yoshinori Ono commented on the issue. "I witnessed as her thighs made a sudden jump into gigantism in SFIII. When we first put her in the game, her sprite was just an outline and her thighs weren't that big...but as the artists starting coloring her in, her legs got thicker and thicker." However, they all felt the larger legs increased the expressiveness of her animations. Regarding then-upcoming Street Fighter IV, Ono said the "character designer, [Daigo] Ikeno, is kind of into thick girls, so as an artist he feels that the most beautiful thighs he can give Chun-Li would be of the wide variety."

Chun-Li sprite's panty-flashing animation frames have been censored for the home console releases by Nintendo. In response to fans that were disappointed with Chun-Li's absence from Street Fighter III, Capcom added her to the 3rd Strike version of the game. Since her main designer, Akiman, was busy with other assignments, she was redesigned by other members from the staff; Chun Li the most time and effort out of all characters. Her inclusion into Street Fighter EX was deemed natural by the studio Arika, with producer Ichiro Mihara describing her as one of the three essential Street Fighter characters along with Ryu and Ken.

In the Street Fighter Alpha games, where she was redesigned by Eri "Erichan" Nakamura, Chun-Li wears a sleeveless tight outfit, her arms and upper body were visibly much stronger than those of any other female character in the franchise, however many artists choose to depict her as petite and slim, in official and unofficial artworks alike, drawing only her legs strong due to her emphasis on kicking moves. An early version of Chun-Li in Street Fighter IV was reworked following complaints from location tests that she was not "cute". Ono later announced Chun-Li's controversial face in Marvel vs. Capcom: Infinite would be also corrected based on a negative feedback from the fans.
