铁十字勋章（德语: Eisernes Kreuz）是由普鲁士国王腓特烈·威廉三世创建的德国军事勋章，于1813年3月10日首次颁发。铁十字勋章曾经在拿破仑战争、普法战争、第一次世界大战，以及第二次世界大战等多次德国参与的会战中颁发。不过铁十字勋章自1945年5月之后就没有再颁发过。

铁十字勋章或许最会被世人联想为纳粹德国的勋章。然而铁十字本身源自条顿骑士的一个手十字饰物，大约自1870年以后成为德国三军的通用标志。铁十字在德国文化中是有力的军事象征，并且于1955年被战后重组的德国联邦国防军再次采用。

The Iron Cross (German:  Eisernes Kreuz , abbreviated EK) was a military decoration in the Kingdom of Prussia, and later in the German Empire (1870–1918) and Nazi Germany (1939–1945). It was established by King Friedrich Wilhelm III of Prussia and first awarded on 10 March 1813 during the Napoleonic Wars (EK 1813). The recommissioned Iron Cross was also awarded during the Franco-Prussian War (EK 1870), World War I (EK 1914), and World War II (EK 1939, re-introduced with a swastika added in the center). The Iron Cross was normally a military decoration only, though there were instances of it being awarded to civilians for performing military functions. Two examples of this were civilian test pilots Hanna Reitsch who was awarded the Iron Cross 2nd Class and 1st Class and Melitta Schenk Gräfin von Stauffenberg, who was awarded the Iron Cross 2nd Class, for their actions as pilots during World War II.
