Dzhankoi Raion (Ukrainian: Джанкойський район, Russian: Джанкойский район, Crimean Tatar: Canköy rayonı) is one of the 25 regions of Crimea, currently subject to a territorial dispute between the Russian Federation and Ukraine.

The city of Dzhankoi is the raion's administrative centre, but it is excluded from the region and forms a separate municipality.

The North-Crimean canal (the main waterway of northern Crimea supplying the republic with water from the Dnieper river) runs through the district.

On 16 August 2022, during the Russian invasion of Ukraine, a large temporary ammunition store of the Russian forces in the villages of Maiske and Azovske was attacked causing secondary explosions and fires that burned into the next day.

In July 2020, Ukraine conducted an administrative reform throughout its de jure territory.
