The effect of high pressures, up to 40 GPa, on the crystal structure and lattice dynamics of ${\mathrm{AlB}}_{2}$ was studied by synchrotron x-ray powder diffraction, Raman spectroscopy, and first-principles calculations. There are no indications for a pressure-induced structural phase transition. The Raman spectra of the metallic sample exhibit a well-defined peak near $980{\mathrm{cm}}^{\ensuremath{-}1}$ at 0 GPa, which can be attributed to the Raman-active ${E}_{2g}$ zone-center phonon.
