  We present the analysis how Ho\v{r}ava gravity and plasma influence the
strong lensing phenomena around Kehagias-Sfetsos (KS) black holes. Using the
semi-analytical Bozza method of strong lensing limit, we determine the multiple
images, namely their separation S, and magnification R. We apply our
calculations to the case of supermassive black hole having mass $M=6.5\times
10^{9}\textrm{M}_\odot$ and being at distance $d_0=16.8\textrm{Mpc}$ from
observer corresponding to those observed in M87. We show that the sensitivity
of image magnification, image separation, and shadow angular size on KS
parameter $\omega$ and plasma parameter $k$ are of order from $1\%$ to $10\%$
for $R$ and $~\,16\%$ for $S$.
