Amberd () is a 10th-century fortress located above sea level, on the slopes of Mount Aragats at the confluence of the Arkashen and Amberd rivers in the province of Aragatsotn, Armenia. The name translates to fortress in the clouds in Armenian. It is also the name incorrectly attributed to Vahramashen Church, the 11th-century Armenian church near the castle. The village of Byurakan is from the site of Amberd.
