Kūshankū (クーシャンク, 公相君) also called Kūsankū (クーサンクー) or Kankū-dai (観空大), is an open hand karate kata that is studied by many practitioners of Okinawan Karate. In many karate styles, there are two versions of the kata: Kūsankū-shō and Kūsankū-dai. The name Kūsankū or Kōsōkun (公相君) is used in Okinawan systems of karate, and refers to a person by the name of Kūsankū, a Chinese diplomat from Fukien who is believed to have traveled to Okinawa to teach his system of fighting. In Japanese systems of karate, the kata has been known as Kankū (translated as gazing heavenward, viewing the sky, or contemplating the sky) ever since it was renamed in the 1930s by Funakoshi Gichin. This kata is also practiced in Tang Soo Do and is pronounced something like Kong Sang Koon () in Korean according to the hanja pronunciation of . Due to its difficulty, this kata is often reserved for advanced students. One of its distinguishing features is the jump, which incorporates two kicks.

Kūsankū is a cornerstone of many styles of karate. It is characterized by the use of flowing techniques that resemble those found in White Crane Kung Fu; it also has a wide variety of open-handed techniques. In Matsubayashi-ryu karate, the kata is known for its flying kick and its "cheating" stance, which robs the opponent of opportunities to attack by extending one leg along the ground and squatting as low as possible on the other (ura-gamae). One possible bunkai for this technique allows the practitioner to escape a bear-hug from behind by twisting and dropping out of their grasp. The hand techniques that accompany the stance block the head, while allowing for a strike to the groin, knee, or foot. Because of the complexity of its techniques, Kūsankū is the highest ranking and most complex kata in Matsubayashi-ryū, and is said to take more than ten years to master.
