  We construct flipped SU(5) GUT models as Type IIB flux vacua on $\Z_2\times
\Z_2$ orientifolds. Turning on supergravity self-dual NSNS and RR three-form
fluxes fixes the toroidal complex structure moduli and the dilaton. We give a
specific example of a three-generation flipped SU(5) model with a complete
Higgs sector where supersymmetry is softly broken by the supergravity fluxes in
the closed string sector. All of the required Yukawa couplings are present if
global U(1) factors resulting from a generalized Green-Schwarz mechanism are
broken spontaneously or by world-sheet instantons. In addition, the model
contains extra chiral and vector-like matter, potentially of mass
$\mathcal{O}(M_{string})$ via trilinear superpotential couplings.
