Aleksey Pavlovitch Hansky (Алексей Павлович Ганский; 20 July 1870, in Odessa – 11 August 1908, in Simeiz) was an astronomer from the Russian Empire.

For observations, experiments and astrophotography, Hansy climbed Mont Blanc more than ten times.

Early in 1908 he accepted a position at Simeiz Observatory, which was founded in 1900, and moved there in May 1908.

After embarking on a new research program he died in August of a heart attack while swimming in the Black Sea.
