Alexandru Al. Ioan Cuza (also known as Alexandru A. Cuza or Sașa Cuza; 1862 or 1864 – 1889) was a Romanian aristocrat and politician. He was the eldest son of Domnitor Alexandru Ioan Cuza, by his mistress Maria Catargi-Obrenović, and adopted by Cuza's wife Elena Rosetti-Cuza. His father's rule was the earliest political union between the two Danubian Principalities (Wallachia and Moldavia), which was to form the Kingdom of Romania in 1881. When Alexandru Ioan was ousted and replaced with Carol of Hohenzollern (1866), Alexandru Al. Ioan followed him into exile. He settled back in Romania after his father's death, attempting to create a current of opinion against Carol. He later helped journalists and in founding the anti-Carlist newspaper Adevărul.
