We report the observation of the doubly Cabibbo-suppressed decay D + → K + π – π + in data from Fermilab charm hadroproduction experiment E791. With a signal of 59 ± 13 events we measured the ratio of the branching fraction for this mode to that of the Cabibbo-favored decay D + → K - π + π + to be B (D + → K + π - π + ) / B ( D + → K - π + π + ) = (7.7 ± 1.7 ± 0.8) × 10 -3 . A Dalitz plot analysis was performed to search for resonant structures.
