Staurakios or Stauracius (; died January 11, 812) was Byzantine Emperor from July 26 to October 2, 811 in succession to his father, Nikephoros I, who had fallen at the Battle of Pliska. His rule was cut short by a severe wound suffered in the same battle, and he was forced into retirement in a monastery by his brother-in-law, Michael I Rangabe, where he died soon after.
Staurakios (or Stauracius) (; died on 3 June 800) was a Byzantine eunuch official, who rose to be one of the most important and influential associates of Byzantine empress Irene of Athens (r. 797–802). He effectively acted as chief minister during her regency for her young son, Emperor Constantine VI (r. 780–797) in 780–790, until overthrown and exiled by a military revolt in favour of the young emperor in 790. Restored to power by Constantine along with Irene in 792, Staurakios aided her in the eventual removal, blinding, and possible murder of her son in 797. His own position thereafter was threatened by the rise of another powerful eunuch, Aetios. Their increasing rivalry, and Staurakios's own imperial ambitions, were only resolved by Staurakios's death.
