A knee strike (commonly referred to simply as a knee) is a strike with the knee, either with the kneecap or the surrounding area. Kneeing is a disallowed practice in many combat sports, especially to the head of a downed opponent. Styles such as Muay Thai and several mixed martial arts organizations allow kneeing depending on the positioning of the fighters.

The straight knee (also known as a front knee) is a typical knee strike, and involves thrusting the front of the knee into the head or body of an opponent. The straight knee can be applied from a stand-up position both when the combatants are separated, or when they are clinching. A particularly effective clinching position for throwing front knee is the double collar tie, where the head of the opponent is controlled. On the ground, front knees can be effective from a few top positions such as the Side control and north-south position. Typical targets for the front knee include the head, hips, ribs, solar plexus, stomach and thighs. In Muay Thai, a double collar tie with a front knee to the face was traditionally called Hak Kor Aiyara. The groin is widely considered the key target for knee strikes and clinch knee attacks in a street fight according to karate, tae kwon do, muay thai, and many other martial arts.

The curved knee (also sometimes called a side knee or roundhouse knee) is similar to the front knee except that it does not use a forward thrusting motion, but is instead rotated from the outside. Whereas the front knee needs some space in between the combatants to be performed, the curved knee can be executed from a minimal distance, such as in a close clinch. This technique is often employed when an opponent is attempting to protect from a straight knee. Typical targets include floating ribs, hips, and the side of the abdomen.
