We implement inflation within a realistic supersymmetric SO(10) model in which the doublet-triplet splitting is realized through the Dimopoulos-Wilczek mechanism, the MSSM {mu} problem is resolved, and higgsino mediated dimension five nucleon decay is heavily suppressed. The cosmologically unwanted topological defects are inflated away, and from {delta}T/T, the B - L breaking scale is estimated to be of order 1016 - 1017 GeV. Including supergravity corrections, the scalar spectral index ns = 0.99 {+-} 0.01, with dns/dlnk {<=} 10-3.
