The rear naked choke (RNC) is a chokehold in martial arts applied from an opponent's back. Depending on the context, the term may refer to one of two variations of the technique; either arm can be used to apply the choke in both cases. The word "naked" in this context suggests that, unlike other strangulation techniques found in Jujutsu/Judo, this hold does not require the use of a keikogi ("gi") or training uniform.

The choke has two variations: in one version, the attacker's arm encircles the opponent's neck and then grabs his own biceps on the other arm (see below for details); in the second version, the attacker clasps his hands together instead after encircling the opponent's neck.

This variant is considered to be a "blood choke" because it restricts blood flow to the brain via the carotid arteries. When done correctly, it can cause temporary unconsciousness in a few seconds. The following is a description of this technique using the left arm.

When applied properly unconsciousness occurs in less than 10 seconds and recovery from the choke is just as quick.

The placement of the legs usually falls into two categories. The first is a body lock. The attacker places one of his legs across the stomach or lower chest of the victim. He then places his other leg over his own shin, creating a figure-four with his legs. This allows him to limit movement and stay close to the back of his victim. This technique was used by Anderson Silva against Dan Henderson and by Jim Miller against Melvin Guillard. The other common technique is known as using "hooks". In this version the attacker places his legs inside of the victim's legs. He then moves his legs out, placing his shin behind the victim's knees, essentially using his shins and feet as hooks to control the victim's legs.

This variation (also known as Palm to Palm) has the supporting hand clasp the hand of the choking arm, allowing more pressure to be applied to the neck, but losing some of the control of the head. This alters the choke somewhat so that it is more likely to be applied as an airway-restricting choke or mixed blood and air choke, which results in more pain but a slower choke-out. As such, this technique is less frequently used at advanced levels in Judo. Nonetheless, it has seen some successful applications in mixed martial arts competition: for instance, it was used by Fedor Emelianenko, a heavyweight champion in PRIDE, to defeat Kazuyuki Fujita at the PRIDE 26 event in 2003. Fujita tapped out about five seconds after the choke was applied. He used it again to defeat former UFC Heavyweight Champion Tim Sylvia in 36 seconds. Sylvia tapped out immediately once the choke was sunk in and after the fight described it as being very painful. It was also used by Ultimate Fighting Championship fighter Matt Hughes to defeat Frank Trigg in their second fight which was adapted from a hand-on-biceps version of the rear naked choke. Anderson Silva also used the clasping hands variation when he defeated Dan Henderson in the UFC. Joe Lauzon used this choke in his fight against Melvin Guillard, initially using the standard version, then switching to a palm to palm.
