西里西亚战争是指普鲁士与奥地利及其盟友为争夺西里西亚所发生的战争，为奥地利王位继承战争及七年战争的一部份：

• 第一次西里西亚战争（1740年—1742年）
• 第二次西里西亚战争（1744年—1745年）
• 第三次西里西亚战争（1756年—1763年）

The Silesian Wars (German:Schlesische Kriege) refer to three wars between Prussia and Austria for control of Silesia in the mid-18th century that ended in Prussian victory for all three wars:

The first two can be viewed in the context of the larger War of the Austrian Succession, while the "Third Silesian War" is better known as the Seven Years' War. Silesia was strategically important to Prussia because "it significantly blunted the capacity of Prussia's two chief foes—Austria and Russia—to meddle in Prussian affairs". Prussian victory (and possession of Silesia) foreshadowed a wider struggle for control over the German-speaking peoples that would culminate in the Austro-Prussian War of 1866.
