The motion of an ion in a lower hybrid wave in a tokamak type plasma is studied. For ions with v_⊥ ≥ ω/k_⊥, the motion is stochastic for fields satisfying E/B₀ > ¼(Ω_i /ω)^1/3(ω/k_⊥). Provided that the perpendicular phase velocity, ω/k_⊥, can be slowed down to a few times the ion thermal speed, this stochastic ion motion may be an important mechanism by which injected rf power near the lower hybrid frequency can directly heat the ions.
