  The XENON1T dark matter experiment recently reported 0.65 ton-year exposure
measurement on electron recoils , which shows an excess in $2\sim 3$ KeV
recoils above the detector background. In this paper we present a Pseudo-Dirac
dark matter scenario to explain the excess via inelastic dark matter-electron
scattering. With a KeV scale mass splitting between the two components of the
Pseudo-Dirac dark matter, the slightly excited component can down-scatter on
electrons. The desired dark matter masses are about 10 GeV with a 4 KeV
mass-splitting and unity coupling to electrons, which generate the observed
XENON1T recoil events, give the appropriate dark matter relic abundance and
satisfy collider search limits.
