An analytic formula for the light deflection angle is obtained. For a propagating photon, the deflection angle δφ increases with large values of the Hořava gravity parameter ω. Under the UV limit $${\omega \longrightarrow \infty}$$, deflection angle reduces to the result of usual Schwarzschild case, 4GM/R. It is also found that with increasing scale of astronomical observation system the Hořava-Lifshitz gravity should satisfy |ω M 2|> 1.1725 ×10−16 with 12% precision for Earth system, |ω M 2| > 8.27649 × 10−17 with 17% precision for Jupiter system and |ω M 2| > 8.27650× 10−15 with 0.17% precision for solar system.
