We perform a calculation of the relativistic corrections to the
electromagnetic elastic form factors of the nucleon obtained with various
Constituent Quark Models. With respect to the non relativistic calculations a
substantial improvement is obtained up to Q^2 about 2 (GeV/c)^2.Comment: 10 pages, 6 figures (1a,1b,1c,2a,2b,2c), to be published on Z. Phys.
