  In this paper, we investigate the scalar quasinormal modes of
Ho\v{r}ava-Lifshitz theory with $U(1)$ symmetry in static Anti-de Sitter
spacetime. The static planar and spherical black hole solutions in lower energy
limit are derived in non-projectable Ho\v{r}ava-Lifshitz gravity. The equation
of motion of a scalar field is obtained, and is utilized to study the
quasinormal modes of massless scalar particles. We find that the effect of
Ho\v{r}ava-Lifshitz correction is to increase the quasinormal period as well as
to slow down the decay of the oscillation magnitude. Besides, the scalar field
could be unstable when the correction becomes too large.
