Kurogane (Japanese: 黒鋼), born Yōō (Japanese: 鷹王) in the manga^[1] and Haganemaru (Japanese: 鋼丸) in the anime, is a fictional character from Clamp's manga series Tsubasa: Reservoir Chronicle. Kurogane is a poor tempered ninja from Japan who is obsessed with fighting. His lady, Princess Tomoyo, exiles him to modern Japan where Kurogane joins with the wizard Fai D. Flowright and two teenagers known as Syaoran and Sakura who are in the need of travelling different dimensions. The witch Yuko Ichihara gives them such power at the cost of their most treasured item with Kurogane giving his sword. Across the narrative, Kurogane bonds with the other travelers and learns that his parents were killed by the same people who attacked Syaoran and Sakura's country, making him look for revenge. He also makes cameos in other Clamp's works.

Clamp created Kurogane and Fai with the idea of having strong supporting characters who would assist the younger protagonist Syaoran. He is meant to contrast Fai in terms of design and personality while his fighting skills were based on Clamp's liking of swordsmanship. The character is voiced by Tetsu Inada in Japanese and Christopher Sabat in English.

Despite initial mixed reception to the character's personality, his personal character development allowed audiences to view him in a much more positive light. Kurogane's bonds with the travelling group was well received especially with his backstory revealed. Kurogane's overall character growth was very highly critically received. Sabat's acting as Kurogane was often considered as the best one provided by Funimation for the English dub.
