Lyman Raion (Ukrainian: Лиманський район, romanized: Lymans'kyi raion; Russian: Лиманский район, romanized: Limanskiy raion) was a raion (district) within Donetsk Oblast in eastern Ukraine. Its administrative center was Lyman, which was separately incorporated as a city of oblast significance and did not belong to the district. Its area was 1,018 km (393 sq mi) and its population was approximately 21,881 (2013 est.).

In 2016, Lyman Raion was abolished and merged into Lyman municipality (Lyman urban hromada, formerly Krasnyi Lyman United Territorial Community).

Before 1917, the raion was part of the Kharkov Governorate.

Until May 2016, raion was known as Krasnyi Lyman Raion (Ukrainian: Краснолиманський район). On 19 May 2016, Verkhovna Rada adopted a decision to rename Krasnyi Lyman Raion to Lyman Raion according to the law prohibiting names of Communist origin. Krasnyi Lyman was previously renamed to Lyman according to the same law.
