世界政策（德语：Weltpolitik）是德国在19世纪末的战略，用以取代早前现实政治（德语：Realpolitik）之大陆政策。

此策具有侵略性，令德国与其他欧洲国家屡次发生冲突，间接导致很多强国之间的外交危机，是第一次世界大战的近因之一。

根据世界政策，德国要寻找一个太阳下的位置，借创建一个殖民帝国，与她的工业实力相称、与其他强国一较高下。值得注意的是，德国争取扩建德意志帝国海军，企图超越英国皇家海军的实力。鉴于英国作为一个岛国，其生存依赖保持海上力量优势，以维持国土安全及海上补给路线，故德国之海军扩张惹来英国的忌惮,于是，这引起两国争相建造无畏舰，造成军备竞赛。

"Weltpolitik" ("world policy") was the foreign policy adopted by Kaiser Wilhelm II of Germany in 1891, which marked a decisive break with former ' "Realpolitik," and referred to Germany's foreign policy.

The aim of Weltpolitik was to transform Germany into a global power through aggressive diplomacy, the acquisition of overseas colonies, and the development of a large navy. The origins of the policy can be traced to a Reichstag debate on 6 December 1897 during which German Foreign Secretary Bernhard von Bülow stated, "in one word: We wish to throw no one into the shade, but we demand our own place in the sun." ("Mit einem Worte: wir wollen niemand in den Schatten stellen, aber wir verlangen auch unseren Platz an der Sonne.")
