We measure the lifetime of the 8s level of {sup 210}Fr atoms on a magneto-optically trapped sample with time-correlated single-photon counting. The 7P{sub 1/2} state serves as the resonant intermediate level for two-step excitation of the 8s level completed with a 1.3-{mu}m laser. Analysis of the fluorescence decay through the 7P{sub 3/2} level gives 53.30{+-}0.44 ns for the 8s level lifetime.
