Cleopatra of Pontus (110 BC – after 58 BC) was a Pontian Princess and a Queen consort of Armenia.

She was one of the daughters of King Mithridates VI of Pontus and Queen Laodice. Cleopatra is sometimes known as Cleopatra the Elder, to distinguish her from her sister of the same name and was born and raised in the Kingdom of Pontus. She was the wife of the Armenian King Tigranes the Great.

She married Tigranes in 94 BC, cementing the alliance between Pontus and Armenia. She played a decisive role in the life of Tigranes and all of Armenia. Cleopatra bore Tigranes three sons: Zariadres, Artavasdes II of Armenia, Tigranes and two daughters. One daughter married King Pacorus I of Parthia and the other daughter married King Mithridates I of Media Atropatene.

Unlike Mithridates, Tigranes had a different foreign policy towards the Roman Republic based on his interests and he eventually signed a treaty with Rome following the Battle of Artaxata in 68 BC, as a result of which Cleopatra, under the influence of her father, instigated their sons to betray Tigranes. In 66 BC, Pompey captured the younger Tigranes and took him to Rome as a hostage. Tigranes later escaped in 58 BC with the assistance of Publius Clodius Pulcher. Roman historian Asconius described the event. The sons attempted unsuccessfully to seize the throne from Tigranes; Zariadres and his younger brother were executed by Tigranes.

Cleopatra escaped to her father and lived the rest of her life in Pontus.
