A process for producing diesel fuel from a diesel hydrocarbon feed. Hydrogen is fed concurrently with the feed to a first hydrogenation zone (16) in the presence of a hydrogenation catalyst (22). Liquid effluent from the first hydrogenation zone is then passed to a second hydrogenation zone (18), wherein the liquid effluent is contacted countercurrently with hydrogen in the presence of a hydrogenation catalyst (23). Preferred hydrogenation catalysts are those comprising non-noble metals in the first hydrogenation zone, and may comprise noble or non-noble metals in the second hydrogenation zone.
