Okny was founded in the end of the 19th century. The area was settled after 1792, when the lands between the
Southern Bug and the
Dniester were transferred to Russia according to the
Iasi Peace Treaty. The area was included in
Tiraspol Uezd, which belonged to
Yekaterinoslav Viceroyalty until 1795,
Voznesensk Viceroyalty until 1796,
Novorossiya Governorate until 1803, and
Kherson Governorate until 1920. In 1834, the area was transferred to newly established
Ananyiv Uezd. In 1919, Okny was renamed Krasni Okny. On 16 April 1920,
Odesa Governorate split off, and Ananyiv Uezd was moved to Odesa Governorate, where it was abolished in 1921. In 1923,
povits in
Ukrainian Soviet Socialist Republic were abolished, and the governorates were divided into
okruhas. Krasni Okny was included into
Balta Okruha. On 3 July 1923 Alexiivka Raion with the administrative center in Krasni Okny was established. On 26 November 1924, Balta Okruha was abolished, and the area was transferred into newly established
Moldavian Autonomous Soviet Socialist Republic. The raion was later renamed Krasni Okny. In 1940, Krasni Okny Raion was transferred to Odesa Oblast. On 19 May 2016,
Verkhovna Rada adopted decision to rename Krasni Okny Raion to Okny Raion and Krasni Okny to Okny conform to the law prohibiting names of Communist origin. At the time of disestablishment, the raion consisted of one
hromada,
Okny settlement hromada with the administration in Okny. == Industry ==
