Ovidiopol (Ukrainian: Ові́діополь; Russian: Овидиополь; Turkish: Hacıdere) is a coastal rural settlement in Odesa Oblast, Ukraine.

It is located on the eastern bank of Dniester Estuary directly across Bilhorod-Dnistrovskyi and 40 km (25 mi) west of Odesa.

[1][5] Just before it was captured by Russians, the French military engineer André-Joseph Lafitte-Clavé who visited the area in late 18th century (1787) described that it took them around an hour to swim on a raft from Akkerman to Adzhider.

[1] In 1795 the Russian Empress Catherine the Great by hers decree officially renamed the newly built fortress as Ovidiopol.

[7] The town was named in 1795 after Ovid,[1][5] the Roman poet exiled to the Black Sea coast, based on the claim of Dimitrie Cantemir in his Descriptio Moldaviae (1714–1716) that a local lake near Bilhorod-Dnistrovskyi (probably the Dniester Liman itself, on whose eastern shore the town is located) was named in Romanian Lacul Ovidului (Ovid's Lake).

[5] With the establishment of the fortress, around it appeared a settlement that in 1795 accounted for 266 people and was part of Tiraspol okrug (district) in Voznesensk Namestnichestvo (vice-royalty).
