Kelmentsi Raion (Ukrainian: Кельменецький район) was an administrative raion (district) in the southern part of Chernivtsi Oblast in western Ukraine, on the Romanian border, part of the historical region of Bessarabia.

The raion was abolished on 18 July 2020 as part of the administrative reform of Ukraine, which reduced the number of raions of Chernivtsi Oblast to three.
