  Noncommutative version of D-dimensional relativistic particle is proposed. We
consider the particle interacting with the configuration space variable
$\theta^{\mu\nu}(\tau)$ instead of the numerical matrix. The corresponding
Poincare invariant action has a local symmetry, which allows one to impose the
gauge $\theta^{0i}=0, ~ \theta^{ij}=const$. The matrix $\theta^{ij}$ turns out
to be the noncommutativity parameter of the gauge fixed formulation. Poincare
transformations of the gauge fixed formulation are presented in the manifest
form. Consistent coupling of NC relativistic particle to the electromagnetic
field is constructed and discussed.
