- A feature that helps to identify, tell apart, or describe recognizably; a distinguishing mark or trait.
- Mathematics The integral part of a logarithm as distinguished from the mantissa: The characteristic of the logarithm 6.3214 is 6.

- (algebra, field theory) The minimum number of times that the unit of a field must be added unto itself in order to yield that field's zero, or, if that minimum natural number does not exist, then (the integer) zero.
- A field's characteristic, if non-trivial, must be prime, otherwise the field would not be an integral domain, which fields must be. For example, if a field's characteristic were six, then (1+1)+(1+1)+(1+1) = 0; if 1+1 were labeled A and 1+1+1 were labeled B, then A + A + A = 0, A (1 + 1 + 1) = 0 by distributivity; A B = 0, and the field could not be an integral domain.
From Ancient Greek χαρακτηριστικός (kharaktēristikos), from χαρακτηρίζω (kharaktērizō, “to designate by a characteristic mark”), from χαρακτήρ (kharaktēr, “a mark, character”).
