We have computed the Stark-broadened profiles of the first two Balmer lines ($n=3,4\ensuremath{\rightarrow}2$) of ${\mathrm{C}}^{5+}$. Plasma conditions span the electron density range ${n}_{e}={10}^{17}\ensuremath{-}{10}^{20}$ ${\mathrm{cm}}^{\ensuremath{-}3}$, and $T=20\ensuremath{-}300$ eV. The calculations include ion-dynamic effects, which we find are very important at the lower densities for ${\mathrm{H}}_{\ensuremath{\alpha}}(n=3\ensuremath{\rightarrow}2)$. At the higher densities, the dynamic profiles approach the static ones.
