The Zakharov–Kuznetsov equation in space dimension d≥3 is considered. It is proved that the Cauchy problem is locally well-posed in H s (ℝ d ) in the full subcritical range s>(d-4)/2, which is optimal up to the endpoint. As a corollary, global well-posedness in L 2 (ℝ 3 ) and, under a smallness condition, in H 1 (ℝ 4 ), follow.
