Utilizing astrometric parameters sourced from \textit{Gaia} Data Release 3and radial velocities obtained from various spectroscopic surveys, we identify519 high-velocity stars (HiVels) with a total velocity in the Galactocentricrestframe greater than 70\% of their local escape velocity under the{\tt\string Gala} {\tt\string MilkyWayPotential}. Our analysis reveals that themajority of these HiVels are metal-poor late-type giants, and we show 9 HiVelsthat are unbound candidates to the Galaxy with escape probabilities of 50\%. Toinvestigate the origins of these HiVels, we classify them into four categoriesand consider the impact of the Large Magellanic Cloud (LMC) potential on theirbackward-integration trajectories. Specifically, we find that one of the HiVelscan track back to the Galactic Center, and three HiVels may originate from theSagittarius dwarf spheroidal galaxy (Sgr dSph). Furthermore, some HiVels appearto be ejected from the Galactic disk, while others formed within the Milky Wayor have an extragalactic origin. Given that the LMC has a significant impact onthe orbits of Sgr dSph, we examine the reported HiVels that originate from theSgr dSph, with a few of them passing within the half-light radius of the SgrdSph.
