He was the seventh (but fourth surviving) son of Johann, Duke of Saxe-Weimar, and Dorothea Maria of Anhalt.
His regnal name Albert IV derives from the numbering of the duchy of Saxony as a whole, not specifically to the succession in Saxe-Eisenach. Albrecht received his first instruction from the Field Marshal Frederick of Kospoth. The two princes travelled to France and Switzerland.
After his return in 1621, Albrecht occupied himself with administrative duties until 1626.
In Weimar on 24 June 1633 Albrecht married Dorothea of Saxe-Altenburg, daughter of Frederick William I, Duke of Saxe-Weimar. The marriage was childless.
He died four years later, after which his state was merged with Saxe-Weimar under Wilhelm of Saxe-Weimar.
