Vadzim Henadzevich Makhneu (Belarusian: Вадзім Генадзевіч Махнеў) or Vadim Makhnev Russian: Вадим Махнев; born 21 December 1979) is a Belarusian flatwater canoeist who has competed since 2000.

Competing in three Summer Olympics, he won four medals with a gold (K-4 1000 m: 2008), a silver (K-2 200m: 2012) and two bronzes (K-2 500 m: 2004, 2008).

In their first season together, the pair won the 500 m silver medal at the world championships in Gainesville, USA.

This decision was amply rewarded in 2005 when the Belarus K-4 500 m crew of Piatrushenka/Abalmasau/Turchyn/Makhneu were crowned first European and then world champions.

In 2005, Makhneu married Alina, a receptionist of the hotel he had lived in while training in Mozyr.
