We study the non-extensive Tsallis statistics and its applications to QCD and high energy physics, and analyze the
possible connections of this statistics with a fractal structure of hadrons. Then, we describe how scaling properties of
Yang-Mills theories allow the appearance of self-similar structures in gauge fields, which actually behave as fractals.
The Tsallis entropic index, q, is deduced in terms of the field theory parameters, resulting in a good agreement with
the value obtained experimentally.
