Stanislav Popov Radonjić (Serbian Cyrillic: Станислав Радоњић) or Staniša Stanišić (Станиша Станишић[1]); 1690 – 17 March 1758), known as Stano (Стано), was a vojvoda, serdar and the first guvernadur (governor) of the Prince-Bishopric of Montenegro from 1756 until he died in 1758, serving Metropolitan Sava II Petrović-Njegoš.
He was elected by the Montenegrin zbor in Cetinje following the victory against the Ottomans at Bijele Poljane, where he killed their commander, Ahmet-paša.
The diploma that confirmed his title as gubernadur appears: "Did wonders in the battlefield – Bijele poljane".
He died in St. Petersburg and was buried with great honor by the Russian court in a tomb bearing the family coat of arms.
Seen off with gifts and medals, Stano visited Pope Benedict XIV (1740–1758), seeking assistance in an amount of 50,000 SCA for reconstruction and maintenance of monasteries on the territory from Kotor to Venetian Albania, which was then under the religious authority of Cetinje mitropholy.
