The Ardennes (French: Ardenne [aʁdɛn] ^ⓘ; Dutch: Ardennen [ɑrˈdɛnə(n)] ^ⓘ; German: Ardennen; Walloon: Årdene [ɑːʀdɛn]; Luxembourgish: Ardennen [ɑʁˈdænən]), also known as the Ardennes Forest or Forest of Ardennes, is a region of extensive forests, rough terrain, rolling hills and ridges primarily in Belgium and Luxembourg, extending into Germany and France.

Geologically, the range is a western extension of the Eifel; both were raised during the Givetian age of the Devonian (382.7 to 387.7 million years ago), as were several other named ranges of the same greater range.^[1]

The Ardennes proper stretches well into Germany and France (lending its name to the Ardennes department and the former Champagne-Ardenne region) and geologically into the Eifel (the eastern extension of the Ardennes Forest into Bitburg-Prüm, Germany); most of it is in the southeast of Wallonia, the southern and more rural part of Belgium (away from the coastal plain but encompassing more than half of the country's total area). The eastern part of the Ardennes forms the northernmost third of the Grand Duchy of Luxembourg, also called "Éislek" (German: Oesling). On the southeast the Eifel region continues into the German state of the Rhineland-Palatinate.

The trees and rivers of the Ardennes provided the charcoal industry assets that enabled the great industrial period of Wallonia in the 18th and 19th centuries, when it was arguably the second great industrial region of the world. The greater region maintained an industrial eminence into the 20th century, after coal replaced charcoal in metallurgy. The strategic position of the Ardennes has made it a battleground for European powers for centuries; it was the site of major battles during both World Wars.
