  We study the thermodynamic properties of the black hole derived in
Ho\v{r}ava-Lifshitz (HL) gravity without the detailed-balance condition. The
parameter $\Xi=\epsilon^2$ in the HL black hole plays the same role as that of
the electric charge in the RN-AdS black hole. By analogy, we treat the
parameter $\Xi$ as the thermodynamic variable and obtain the first law of
thermodynamics for the HL black hole. Although the HL black hole and the RN-AdS
black hole have the similar mass and temperature, due to their very different
entropy the two black holes have very different thermodynamic properties. By
calculating the heat capacity and the free energy we analyze the thermodynamic
stability of the HL black hole.
