Lüneburg Heath (German: Lüneburger Heide, pronounced [ˈlyːnəbʊʁɡɐ ˈhaɪdə] ^ⓘ) is a large area of heath, geest, and woodland in the northeastern part of the state of Lower Saxony in northern Germany. It forms part of the hinterland for the cities of Hamburg, Hanover and Bremen and is named after the town of Lüneburg. Most of the area is a nature reserve. Northern Low Saxon is still widely spoken in the region.

Lüneburg Heath has extensive areas, and the most yellow of heathland, typical of those that covered most of the North German countryside until about 1800, but which have almost completely disappeared in other areas. The heaths were formed after the Neolithic period by overgrazing of the once widespread forests on the poor sandy soils of the geest, as this slightly hilly and sandy terrain in northern Europe is called. Lüneburg Heath is therefore a historic cultural landscape. The remaining areas of heath are kept clear mainly through grazing, especially by a North German breed of moorland sheep called the Heidschnucke. Due to its unique landscape, Lüneburg Heath is a popular tourist destination in North Germany.

Lüneburg Heath covers an area which includes the districts (Landkreise) of Celle, Gifhorn, Heidekreis, Uelzen, Lüneburg, Lüchow-Dannenberg, southeast Rotenburg (the town of Visselhövede, Fintel, part of the municipality of Scheeßel and the eastern half of Bothel) and the rural district of Harburg. The easternmost fringes of the Stade Geest belonging to Landkreis Verden are called the Linteln Geest (Lintelner Geest) or Verden Heath (Verdener Heide) and form part of the municipality of Kirchlinteln. This region has no sharply defined boundary with the Lüneburg Heath.

Today the area is a popular tourist destination. Contributing to this are the theme park, Heidepark Soltau, the Walsrode Bird Park, the Serengeti Safari Park at Hodenhagen, Snow Dome Bispingen, and a Center Parc as well as the many farms offering holiday stays, making the Lüneburg Heath especially popular for families. Another group of tourists are the elderly on free guided bus tours (Kaffeefahrten), stopping for coffee and wool plaids at a farm before touring Lüneburg for an hour.

The Kunststätte Bossard in the Nordheide near Jesteburg is an expressionist Gesamtkunstwerk open to the public.

The memorial exhibition at the former Bergen-Belsen concentration camp near the town of Bergen is also located in the Lüneburg Heath.

From a geographical point of view, Lüneburg Heath is a specific natural region, that is an area distinguished by a specific combination of abiotic factors (climate, relief, water resources, soil, geology) and biotic factors (flora and fauna). Lüneburg Heath is a sub-division of the North European Plain. In the list of the major natural regions of Germany issued by the Federal Office for Nature Conservation (Bundesamt für Naturschutz) it is region number D28.

Lüneburg Heath lies between the rivers Elbe to the north, the Drawehn to the east, the Aller to the south and southwest, the middle course of the Wümme to the west and the Harburg Hills (Harburger Berge) to the northwest.
