Albert (Latin Albertus, German Albrecht; 1236 ? 1279), called the Tall (Latin Longus), was duke of Brunswick-Lüneburg.
Albert was the second son of Otto the Child, Duke of Brunswick-Lüneburg. When his father died in 1253, he was the oldest surviving son, and took over the rule of the duchy; later his younger brother John joined him. In 1267, the brothers agreed to divide the duchy, which happened in 1269. Albert received the southern half, including Calenberg, Helmstedt, the Harz, and Göttingen. The City of Brunswick was to remain common property of the brothers.
Albert was succeeded by his elder three sons; the younger three sons joined the Church.
Albert married Elizabeth, daughter of Henry II, Duke of Brabant, in 1254. Elizabeth died childless in 1261. He then married Adelheid, daughter of Boniface III, Margrave of Montferrat, around 1263, and they had the following children:
* Henry (ca. 1267-1322)
* Albert (ca. 1268-1318)
* William (ca. 1270-1292)
* Otto (died ca. 1346)
* Matilda, married Henry III, Duke of Silesia-Glogau
* Lothar (died 1335), Grand Master of the Teutonic Order
