We have magneto-optically trapped the nine stable isotopes of xenon. Using the Zeeman slowing method to decelerate a beam of xenon atoms in the metastable 6s 3/2 [3/2${]}_2$ state (notation representing nl ${\mathit{J}}_{\mathrm{core}}$ [K=${\mathit{J}}_{\mathrm{core}}$+l${]}_{\mathit{J}}$), we load our trap to a collisionally limited density of more than ${10}^{10}$ atoms/${\mathrm{cm}}^3$. The two odd isotopes are trapped without a repumping frequency, even though they have hyperfine structure. The sensitivity of the trapping process to the laser frequency is exploited to make accurate measurements of the isotope shifts for the 6s 3/2 [3/2${]}_2$→6p 3/2 [5/2${]}_3$ laser-cooling transition and of the hyperfine constants for ${}_{}{}^{131}{}_{}{}^{}\mathrm{Xe}$.
