Persida Karađorđević née Nenadović (Serbian Cyrillic: Персида Ненадовић; 15 February 1813 – 29 March 1873) was the Princess of Serbia as the wife of Alexander Karađorđević, who ruled the Principality of Serbia from his election on 14 September 1842 until his abdication on 24 October 1858.

On 1 June 1830 in Hotin, Bessarabia, at the age of 17, she married Alexander Karađorđević (1806-1885), the youngest son of Karađorđe Petrović and his wife, Jelena Jovanović (1771-1842).

In 1858, Prince Alexander came into conflict with members of the Council, with the result that he was compelled to abdicate in favor of Miloš Obrenović, who returned to power for the second time.

In 1912, their son King Peter ordered the remains of Princess Persida and Prince Alexander to be moved to the Church of St. George in Oplenac.

For her charitable work and cultural activities, Turkish Sultan awarded her the Order of the Padishah Portrait in 1864.
