Bagtyýarlyk şäherçesi, formerly known as Ücajy (romanized Russian Uch-Adzhi), is a town in Baýramaly District, Mary Province, Turkmenistan. The town was known as Üçajy (Cyrillic Turkmen Үчаҗы) until 20 September 2012, when by Parliamentary Resolution No. 331-IV it was renamed Bagtyýarlyk. The record high temperature of 48.4 °C was registered on July 7, 2021.

Etymology

The original name of the settlement is a compound of two words, üç and ajy, which mean "three" and "bitter", respectively. Atanyyazow explains that the first three water wells drilled here, when the rail line was being extended to Çärjew, yielded bitter water, hence the name, which was later applied to the town and a nearby state farm. The word bagtyýarlyk simply means "having luck or happiness". This name stems from the Persian word "Bakhtyar" (بختیار) meaning "luck or happiness", plus the suffix "-lyk", denoting one who has luck or happiness.
