日德兰海战（英语：Battle of Jutland；德国称为斯卡格拉克海峡海战，Skagerrakschlacht）；1916年5月31日─6月1日）是英国皇家海军（也包括皇家澳大利亚海军与皇家加拿大海军的舰只）与德意志帝国海军在距离丹麦日德兰半岛西海岸约80英里（128公里）的北海海域爆发的一场海战。这是第一次世界大战中最大规模，以及史上参战战舰数量最庞大的海战，也是这场战争中交战双方唯一一次全面出动的舰队主力决战。

德国计划以弗朗茨·冯·希佩尔海军中将率领的5艘战斗巡洋舰为主力的战队，引诱戴维·贝蒂海军中将率领以6艘战列巡洋舰及4艘无畏舰为主力的英国战队进入公海舰队所设的陷阱。但该作战计划由于德国海军密码被英方破译，英国本土舰队同时出动。

The Battle of Jutland (German:Skagerrakschlacht, the Battle of Skagerrak) was a naval battle fought by the British Royal Navy's Grand Fleet under Admiral Sir John Jellicoe, against the Imperial German Navy's High Seas Fleet under Vice-Admiral Reinhard Scheer during the First World War. The battle was fought from 31 May to 1 June 1916 in the North Sea, near the coast of Denmark's Jutland Peninsula. It was the largest naval battle and the only full-scale clash of battleships in the war. It was the third fleet action between steel battleships, following the smaller but more decisive battles of the Yellow Sea (1904) and Tsushima (1905) during the Russo-Japanese War.
