Victor Mihalachi (born 24 February 1989) is a Romanian sprint canoeist who has competed since the late 2000s.

He won 4 gold medals at the ICF Canoe Sprint World Championships, two at the 2010 ICF Canoe Sprint World Championships in Poznań, earning them in the C-2 500 m and C-2 1000 m events, one at the 2011 ICF Canoe Sprint World Championships in Szeged (in the C-2 500 m) and one at the 2014 ICF Canoe Sprint World Championships in Moscow (in the C-2 1000 m).

He has also won three European gold medals (C-2 500 m 2010, 2011; C-2 1000 m 2012), 5 silvers (C-2 500 m 2012, 2013, 2014, 2016, 2017) and 4 bronze (C-2 1000 m 2010, 2011, 2013, C-2 200 m 2014).

He and his teammate Liviu Dumitrescu have worn lucky caps with marijuana leaves on to race in.

He competed for Moldova as a junior but switched to competing for Romania as he felt he was not receiving enough support from the Moldovan Canoeing Federation.
