At ambient conditions, CsV$_3$Sb$_5$ shows a charge-density wave (CDW) transition at $T_{\\rm CDW}=94.5$ K and superconducts below $T_C = 3.34$ K. In our study, when the uniaxial strain $\\varepsilon$ is varied from $-0.90\\%$ to $0.90\\%$, $T_C$ monotonically increases by $\\sim 33\\%$ from 3.0 K to 4.0 K, giving rise to the empirical relation $T_C (\\varepsilon)=3.4+0.56\\varepsilon+0.12\\varepsilon^2$.
