Reciprocal may refer to:
- Multiplicative inverse In mathematics, a multiplicative inverse or reciprocal for a number x, denoted by 1⁄x or x −1, is a number which when multiplied by x yields the multiplicative identity, 1. The multiplicative inverse of a fraction a⁄b is b⁄a. For the multiplicative inverse of a real number, divide 1 by the number. For example, the reciprocal of 5 is one, in mathematics, the number 1/x, which multiplied by x gives the product 1, also known as a reciprocal
- Reciprocal (grammar) A reciprocal is a linguistic structure that marks a particular kind of relationship between two noun phrases. In a reciprocal construction, each of the participants occupies both the role of agent and patient with respect to each other.

- Reciprocal determinism Reciprocal determinism as a theory initially set forth the proposition that co-jointly; a person's behavior and the social environment creates a dialectic that determines the transformative adaptibility of the ego. Bandura accepts the possibility of an individual's behavior being conditioned through the use of consequences. At the same time he, a theory in psychology

- Reciprocating engine A reciprocating engine, also often known as a piston engine, is a heat engine that uses one or more reciprocating pistons to convert pressure into a rotating motion. This article describes the common features of all types. The main types are: the internal combustion engine, used extensively in motor vehicles; the steam engine, the mainstay of the or piston engine in mechanics

- Reciprocal Aircraft heading In navigation, a course is the intended path of a vehicle over the surface of the Earth. The course is the intended path of a vehicle of a line drawn on a chart representing the intended path. It is expressed as the angle measured from an object clockwise from 0° through 360° to the line. The object is often the true north. The course is, 180 degrees (the opposite direction) from a stated heading.
