AB  - Using e^+e^- annihilation data corresponding to an integrated luminosity of 4.5 fb^−1 collected with the BESIII detector at center-of-mass energies between 4.600 and 4.699 GeV, the first amplitude analysis of the charmed baryon decay Λ_c^+ → p K_S^0 π^0 is performed. The processes Λ_c^+ → p K̅^*(892)^0, Λ_c^+ → Δ(1600)^+ K_S^0, and Λ_c^+ → N(1710)^+ K_S^0 are identified with statistical significances of 12.8σ, 14.5σ, and 6.2σ, respectively. The mass and width of Δ(1600)^+ are measured to be (1520.4 ± 8.8 ± 37.7) MeV and (199.4 ± 26.4 ± 39.9) MeV, respectively. The mass and width of N(1710)^+ are measured to be (1719.7 ± 9.4 ± 9.1) MeV and (72.0 ± 18.0 ± 15.0) MeV, respectively. The branching fractions of these processes are determined to be ℬ[Λ_c^+ → Δ(1600)^+ (→ p π^0) K_S^0] = (8.10 ± 0.80 ± 5.57) × 10^−3, ℬ[Λ_c^+ → N(1710)^+ (→ p π^0) K_S^0] = (1.58 ± 0.48 ± 0.77) × 10^−3, and ℬ[Λ_c^+ → p K̅^*(892)^0 (→ K_S^0 π^0)] = (2.63 ± 0.47 ± 0.29) × 10^−3, where the first uncertainties are statistical and the second systematic.
