Topolnoye (lake) refers to any of several lakes, predominantly in Russia, sharing the common name "Topolnoye" (Russian: Топольное). The name is derived from the Russian word "тополь" (topol'), meaning "poplar tree," suggesting a historical or current presence of these trees in the vicinity of such lakes. While multiple water bodies bear this name, one of the most notable is Topolnoye Lake in Altai Krai, Russia.

Other Topolnoye Lakes
Lesser-known lakes named Topolnoye can be found in various other regions, including other parts of Russia (e.g., in Krasnoyarsk Krai or Tomsk Oblast) and potentially in other Slavic countries. These generally share the same etymological root and are typically smaller or less prominent than the Altai Krai example.
