Volodymir Gustov (Ukrainian: Володимир Густов, sometimes transliterated as Volodymyr Hustov or other permutations; born 15 February 1977 in Kyiv) is a Ukrainian professional road bicycle racer, who last rode for UCI ProTeam Saxo Bank–Tinkoff Bank. He began his career in 2000 with Italian team Fassa Bortolo.

Before the 2002 Tour de Romandie, Gustov was tested with a hematocrit level above fifty percent. This indicates either health problems or doping usage so he was suspended for fifteen days, but in the middle of May, Fassa Bortolo announced that he could ride again. After laboratory tests accredited by the Union Cycliste Internationale (UCI), the governing body of cycling, it was stated that his high hematocrit and hemoglobin values were physiologically determined. As his contract ended prior to the 2006 season, former team mate Ivan Basso arranged for him to ride alongside him at Danish Team CSC.

After being selected for the 2008 Tour de France team, he worked for the two Schleck brothers and Carlos Sastre as the race got into the French Alps and Pyrenees.
