Gothic plate armour (German: Gotischer Plattenpanzer) was the type of steel plate armour made in the Holy Roman Empire during the 15th century.
While the term "Gothic" in art history covers the 12th to 15th centuries, Gothic plate armour develops only during 1420–1440s, when the technological development of armour reached the stage where full plate armour (including movable joints) was made, and national styles of "white armour" began to emerge, specifically German ("Gothic") and Italian (Milanese).
Centers of armour production in the period included Augsburg, Nuremberg and Landshut.
High Gothic armour was worn during the later 15th century, a transitional type called Schott-Sonnenberg style was current during c. 1500 to 1515, and Maximilian armour proper during 1515 to 1525.
Methods of single combat in this type of armour are treated in the German fencing manuals of the period, under the term Harnischfechten ("armoured combat").
