   We prove that every smooth connected complex projective Fano sixfold with nef tangent bundle is rational homogeneous, resolving the Campana–Peternell conjecture in complex dimension six. As a consequence, a connected compact Kähler manifold X with nef holomorphic tangent bundle and dim_ℂX-q̃(X) ≤ 6 has ordinary universal cover F×ℂ^q̃(X), where F is a rational homogeneous manifold and q̃(X) is the maximal irregularity of a connected finite étale cover.
