We perform in this paper a statefinder diagnostic to a dark energy model with
two scalar fields, called "quintom", where one of the scalar fields has a
canonical kinetic energy term and the other has a negative one. Several kinds
of potentials are discussed. Our results show that the statefinder diagnostic
can differentiate quintom model with other dark energy models.
