We introduce the fundamental group F(A) of a unital simple C*-algebra A with a unique normalized trace. We compute fundamental groups F(A) of several nuclear or non-nuclear C*-algebras A. K-theoretical obstruction enables us to compute the fundamental group easily. Our study is essentially based on the computation of Picard groups by Kodaka.
