Prince Albert of Saxe-Altenburg (Albert Heinrich Joseph Carl Viktor Georg Friedrich; Munich, 14 April 1843 – Serrahn, 22 May 1902) was a German prince of the ducal house of Saxe-Altenburg.

Prince Albert was the eldest son (third in order of birth but the only one who survived to adulthood) of Prince Eduard of Saxe-Altenburg (youngest son of Frederick, Duke of Saxe-Hildburghausen) and his second wife, Princess Luise Caroline Reuss of Greiz.

He entered the Russian army early in life, and attained the rank of Major-General in this service, but subsequently exchanged it for the Prussian army, where he became a general of cavalry.

He was first married in Berlin on 6 May 1885 to Princess Marie of Prussia, widow of Prince Henry of the Netherlands.

They had two daughters:

Albert was a conspicuous figure in Berlin society, and was a great favorite due to his "clever" mind, genial disposition, pleasant address, and enthusiasm as a sportsman. Marie died in 1888. Albert later married in Remplin on 13 December 1891 to the wealthy Duchess Helene of Mecklenburg-Strelitz, only daughter of Grand Duchess Catherine Mikhailovna of Russia. They had no children.

The couple spent half of the year in Russia, where he was much missed in Berlin society. In 1896, he and several other prominent social leaders left Berlin as a result of differences they held with Emperor Wilhelm II. He and his family retired to their Schwerin estate. Sources reported that the Emperor′s "arbitrary manners" became so intolerable to Albert and others, as they were used to the days of social courtesy under the old Wilhelm I.
