Alexandrovsk uezd (Russian: Александровскій уѣздъ, romanized: Aleksandrovskiy uyezd; Ukrainian: Олександрівський повіт, romanized: Oleksandrivs'kyi povit) was one of the subdivisions of the Yekaterinoslav Governorate of the Russian Empire.

In March-April 1918, it became part of the Sichova and Oziv lands of the Ukrainian People's Republic.

The territory of the district was reduced due to the allocation of the Gulyaipil county.

At the time of the Russian Empire Census of 1897, Alexandrovsky Uyezd had a population of 271,678.

Of these, 82.5% spoke Ukrainian, 5.7% Russian, 5.2% German, 5.1% Yiddish, 1.2% Belarusian, 0.1% Polish and 0.1% Romani as their native language.
