In mathematics, a coefficient is a multiplicative factor in some term of a polynomial, a series, or an expression; it is usually a number, but may be any expression (including variables such as a, b and c). When the coefficients are themselves variables, they may also be called parameters.

For example, the polynomial \(2x^{2}-x+3\) has coefficients 2, −1, and 3, and the powers of the variable \(x\) in the polynomial \(ax^{2}+bx+c\) have coefficient parameters \(a, b, c\).
