Cleopatra VII Thea Philopator (Koinē Greek: Κλεοπάτρα Θεά Φιλοπάτωρ lit. ' Cleopatra father-loving goddess '; 70/69 BC – 10 August 30 BC) was Queen of the Ptolemaic Kingdom of Egypt from 51 to 30 BC, and its last active ruler. A member of the Ptolemaic dynasty, she was a descendant of its founder Ptolemy I Soter, a Macedonian Greek general and companion of Alexander the Great. Her first language was Koine Greek, and she is the only Ptolemaic ruler known to have learned the Egyptian language. After her death, Egypt became a province of the Roman Empire, marking the end of the last Hellenistic-period state in the Mediterranean, a period which had lasted since the reign of Alexander (336–323 BC).

In 58 BC, Cleopatra presumably accompanied her father, Ptolemy XII Auletes, during his exile to Rome after a revolt in Egypt (a Roman client state) allowed his rival daughter Berenice IV to claim his throne. Berenice was killed in 55 BC when Ptolemy returned to Egypt with Roman military assistance. When he died in 51 BC, Cleopatra began reigning alongside her brother Ptolemy XIII, but a falling-out between them led to an open civil war. Roman statesman Pompey fled to Egypt after losing the 48 BC Battle of Pharsalus in Greece against his rival Julius Caesar (a Roman dictator and consul) in Caesar's civil war. Pompey had been a political ally of Ptolemy XII, but Ptolemy XIII, at the urging of his court eunuchs, had Pompey ambushed and killed before Caesar arrived and occupied Alexandria. Caesar then attempted to reconcile the rival Ptolemaic siblings, but Ptolemy's chief adviser, Potheinos, viewed Caesar's terms as favoring Cleopatra, so his forces besieged her and Caesar at the palace. Shortly after the siege was lifted by reinforcements, Ptolemy XIII died in the Battle of the Nile; Cleopatra's half-sister Arsinoe IV was eventually exiled to Ephesus for her role in carrying out the siege. Caesar declared Cleopatra and her brother Ptolemy XIV joint rulers but maintained a private affair with Cleopatra that produced a son, Caesarion. Cleopatra traveled to Rome as a client queen in 46 and 44 BC, where she stayed at Caesar's villa. After Caesar's assassination, followed shortly afterwards by that of Ptolemy XIV (on Cleopatra's orders), she named Caesarion co-ruler as Ptolemy XV.

In the Liberators' civil war of 43–42 BC, Cleopatra sided with the Roman Second Triumvirate formed by Caesar's grandnephew and heir Octavian, Mark Antony, and Marcus Aemilius Lepidus. After their meeting at Tarsos in 41 BC, the queen had an affair with Antony which produced three children. He carried out the execution of Arsinoe at her request, and became increasingly reliant on Cleopatra for both funding and military aid during his invasions of the Parthian Empire and the Kingdom of Armenia. The Donations of Alexandria declared their children rulers over various erstwhile territories under Antony's triumviral authority. This event, their marriage, and Antony's divorce of Octavian's sister Octavia Minor led to the final war of the Roman Republic. Octavian engaged in a war of propaganda, forced Antony's allies in the Roman Senate to flee Rome in 32 BC, and declared war on Cleopatra. After defeating Antony and Cleopatra's naval fleet at the 31 BC Battle of Actium, Octavian's forces invaded Egypt in 30 BC and defeated Antony, leading to Antony's suicide. When Cleopatra learned that Octavian planned to bring her to his Roman triumphal procession, she killed herself by poisoning, contrary to the popular belief that she was bitten by an asp.

Cleopatra's legacy survives in ancient and modern works of art. Roman historiography and Latin poetry produced a generally critical view of the queen that pervaded later Medieval and Renaissance literature. In the visual arts, her ancient depictions include Roman busts, paintings, and sculptures, cameo carvings and glass, Ptolemaic and Roman coinage, and reliefs. In Renaissance and Baroque art, she was the subject of many works including operas, paintings, poetry, sculptures, and theatrical dramas. She has become a pop culture icon of Egyptomania since the Victorian era, and in modern times, Cleopatra has appeared in the applied and fine arts, burlesque satire, Hollywood films, and brand images for commercial products.
