Tsuyoshi "TK" Kohsaka (高阪 剛 Kōsaka Tsuyoshi?, born March 6, 1970) is a Japanese mixed martial artist and professional wrestler. He has competed in high-profile mixed martial arts promotions, such as the UFC, RINGS, Pancrase, and DEEP. Kohsaka is known for his conditioning and grappling prowess as well as fighting many of the greatest heavyweight and light heavyweight fighters of all time. His "TK guard" position, a precursor to modern butterfly guard, is famous for its efficiency; former UFC champions Frank Shamrock and Maurice Smith have both credited him with having vastly improved their work from that particular position.

Training in judo since highschool, Kohsaka competed extensively during his stay at the Senshu University, where he befriended future world judo champion Hidehiko Yoshida. After graduating, Kohsaka became a professional judoka under the sponsorship of Toray Industries, but was forced to retire after a knee injury. After a year, he joined shoot-style promotion Fighting Network RINGS.
