Composite non-Abelian vortices in N=2 supersymmetric U(2) SQCD are investigated. The internal moduli space of an elementary non-Abelian vortex is CP{sup 1}. In this paper we find a composite state of two coincident non-Abelian vortices explicitly solving the first-order Bogomolny, Prasad and Sommerfield equations. Topology of the internal moduli space T is determined in terms of a discrete quotient CP{sup 2}/Z{sub 2}. The spectrum of physical strings and confined monopoles is discussed. This gives indirect information about the sigma model with target space T.
