Backbreaker refers to a kind of professional wrestling move which sees a wrestler dropping an opponent so that the opponent's back impacts or is bent backwards against a part of the wrestler's body, usually the knee. The standard version of the move sees the wrestler scoop their opponent horizontally before dropping to one knee, slamming the opponent's back on their other knee.

This submission hold, better known as a Torture Rack or simply a rack, sees the attacking wrestler carrying the opponent face-up across his own shoulders, before hooking the opponent's head with one hand and a leg with the other to then pull down on both ends to hyperextend the opponent's back and force a submission. Wrestler Lex Luger was famous for using it as a finisher. Former WWF Superstar Hercules even used this move as a finisher, along with a Full Nelson Submission Hold.

A backbreaker drop variation of this submission move sees the attacking wrestler first hold an opponent up for the Argentine backbreaker rack before dropping to the mat in a sitting or kneeling position, thus flexing the opponent's back with the impact of the drop. Another version sees the wrestler hold their opponent in the Argentine backbreaker rack before dropping into a sitting or kneeling position while simultaneously throwing the opponent off their shoulders, causing the opponent to roll in midair and fall to the mat in a face-down position. Nikki Bella has used both variations as a finisher in WWE.

A variation of the Argentine backbreaker rack, known as the La Reinera, sees the opponent held across the wrestler's upper back rather than his shoulders/neck. Often set up by a tilt-a-whirl, the opponent ends up suspended with one arm hooked behind and both legs hooked by the wrestler's other arm. Rolando Vera was credited with inventing the move.

Another Argentine backbreaker rack variation called the La Atlántida, favored by Mexican luchador Atlantis, sees the attacking wrestler holding the opponent across the shoulders and behind the head in a side-lying position facing towards the rear, then pulling down on the head and one leg to laterally bending the opponent.

A variation of the La Atlántida, sometimes known as the "Accordion Rack", sees the opponent held similarly in a side-lying position facing the rear across the attacking wrestler's shoulders, but with the opponent's lower back curvature directly behind the wrestler's head, and instead of pulling downwards the wrestler will chest fly forward to bend the opponent, sometimes to the point that the opponent's heel touches the head. However, this move is mainly limited to opponents with great flexibility. It was utilized by wrestlers like Awesome Kong.

A backbreaker move in which the wrestler lifts an opponent up into an Argentine backbreaker or an overhead gutwrench backbreaker rack, so the opponent's back is resting on the wrestler's shoulder, with the opponent's head pointing in the direction that the wrestler is facing. The attacking wrestler then drops to a kneeling or sitting position while maintaining the hold, thus jarring the back of the opponent by driving the opponent's spine into the attacking wrestler's shoulder. TNA wrestler Abyss used the Argentine version called the Shock Treatment.

The wrestler stands behind the opponent and puts their head under the opponent's arm, as in a belly-to-back suplex, but raises a knee and brings the opponent back down, so that the opponent's back collides with the knee of the wrestler. The move was popularized by Billy Robinson. Tatsumi Fujinami calls this the Dragon Backbreaker. Cedric Alexander uses a double knee version called the Lumbar Check.
