We report the discovery and follow-up timing observations of two young energetic radio pulsars. PSR J1420-6048 has a period P=68 ms and period derivative P{dot}=83x10^–15, implying a characteristic age τ_c=13 kyr and a surface dipole magnetic field strength B=2.4x10¹² G. PSR J1837-0604 has P=96 ms and P{dot}=45x10^–15, implying τ_c=34 kyr and B=2.1x10¹² G. The two objects have large spin-down luminosities, and, on the basis of an empirical comparison of their properties with those of other young radio pulsars, they are expected to be observable as pulsed γ-ray sources. In fact, they lie within the error circles of γ-ray sources detected by the EGRET instrument on the Gamma Ray Observatory. We show that the pulsars are plausibly associated with the EGRET sources.
