In general, a cross is a figure formed by two intersecting line segments. In linear algebra, a cross is defined as a set of n mutually perpendicular pairs of vectors of equal magnitude from a fixed origin in Euclidean n-space.

The word "cross" is also used to denote the operation of the cross product, so a×b would be pronounced "a cross b."
