Viktor Iosifovich Reneysky (Russian: Виктор Иосифович Ренейский, given name also transliterated Victor and surname Reneyskiy, Reneiski, or Reneischi, born 24 January 1967 in Babruysk) is a sprint canoeist from Belarus who won three Olympic medals for the USSR and Moldova in the C-2 event with his teammate Nikolaï Juravschi.

Reneysky and Juravschi won two gold medals at the 1988 Summer Olympics as competitors for the USSR.

Despite this run of success Reneysky and Juravschi were not selected for the 1992 Barcelona Olympics, having been defeated in the trials by Maseikov and Dovgalenok who justified their inclusion by going on to win the C-2 500 m gold medal.

The following year Reneysky was competing for his native Belarus and won the final world championship gold (C-4 200 m) of his career.

In 2005 in Plovdiv, Bulgaria, he saw his young (average age 19) protégés (Rabchanka / Vaitsishkin / Shcharbak / Vauchetski) beat his own sixteen-year-old C-4 1000 m senior world record.
