Count Alexei (Alexey) Grigoryevich Orlov-Chesmensky was a Russian soldier, general-in-chief, general admiral and statesman, who rose to prominence during the reign of Catherine the Great. His joint victory with Grigory Spiridov and Samuel Greig in the Battle of Chesma put him in the ranks of the outstanding Russian military commanders of all time; and although he lacked naval experience, he was the only authority in those circumstances who could ensure proper co-ordination of action.

The Orlov revolt was a Greek uprising in the Peloponnese and later also in Crete that broke out in February 1770, following the arrival of Russian Admiral Alexey Orlov, commander of the Imperial Russian Navy during the Russo-Turkish War (1768–1774), at the Mani Peninsula. The revolt, a major precursor to the Greek War of Independence, was part of Catherine the Great's so-called "Greek Plan" and was eventually suppressed by the Ottomans.
