Sondernach is a commune in the Haut-Rhin département in Grand Est in north-eastern France.
Located in the parc naturel régional des Ballons des Vosges, the village of Sondernach shares with Mittlach the benefit of being situated on the slopes of a large valley watered by one of the streams forming the Fecht river. The altitude of the centre is between 500 and 600 metres.
Its only immediate neighbour is the commune of Metzeral to the north.
The origin of the village's name is unclear. It could be from der Sonne nahe meaning "near the sun", or zum sundern Ach meaning "near the south stream", Sondernach being the furthest south village in the valley.
Sondernach first appears in archives in the 12th century. Around 1240, the Benedictine Abbey of Munster owned lands in the village. From 1287, the village was made part of the valley community grouping Munster and the ten communes of the Fecht. It was totally destroyed during the First World War, during the battle of Metzeral, in June 1915.
