Recent QCD measurements obtained by the CDF Collaboration at the Tevatron in p anti-p collisions at s**(1/2) = 1.96 TeV are presented. Results on inclusive jet physics are first reported. They include the measurement of the inclusive jet production cross section, a phenomenological study of the underlying event and the measurement of the jet shapes. Some specific processes of interest are then discussed. The measurements of W + jets, gamma gamma and gamma + heavy flavor productions are presented. Finally, the diffractive physics program is approached with reports on the measurements of the diffractive structure function and on the searches for exclusive final states.
