• Pion form factor
• Omnes representation

A new approach to the parameterization of pion form factors is presented and for illustration applied to the pion vector form factor. It has the correct analytic structure, is at low energies consistent with recent high accuracy analyses of pi pi scattering phase shifts and, at high energies, maps smoothly onto the well-known, successful isobar model.
