Landauer's principle connects the logical reversibility of computational operations to physical reversibility and hence to energy dissipation, with important theoretical and practical consequences. We report the first experimental test of Landauer's principle. For logically reversible operations we measure energy dissipations much less than k_{\text{B}} T\log 2, while irreversible operations dissipate much more than k_{\text{B}} T\log 2. Measurements of a logically reversible operation on a bit with energy 30 k_{\text{B}} T yield an energy dissipation of 0.01 k_{\text{B}} T.
