Guloykhi, or Guloy-khi (Ingush: ГӀулой-Хий, romanized: Ghuloy-Khiy) is a river in the Dzheyrakhsky District of the Republic of Ingushetia, a right tributary of the Assa River.

[1][2] The Guloykhi river originates in the eastern part of mountainous Ingushetia.

It flows west along a mountain valley near several medieval tower settlements, most notably Gul, Läzhg, Qoyrakh, Abali, Vovnushki, Koki, and flows into the Assa near Puy and Tkhaba-Yerdy.

[3] A forest mainly covers the left bank of the river.

The mouth of the river is located 103 km along the right bank of the Assa at an altitude of 1112 meters above sea level.
