Vladimir Alexandrovich Efimkin (Russian: Владимир Александрович Ефимкин) (born December 2, 1981, in Kuybyshev) is a Russian retired professional road bicycle racer, who last rode alongside his twin brother Alexander Efimkin on Team Type 1–Sanofi.

However, his major title of the season only came in August, where he won the Volta a Portugal.

After a fabulous breakaway in one of the queen stages, and benefiting from the passivity of the peloton (that were known to underrate the unknown Russian), he captured the yellow jersey and kept it until the end.

In 2008, Efimkin joined the French Ag2r–La Mondiale team, where he was one of the leaders for the Tour de France.

Efimkin quit cycling in the middle of the 2010 season, but came back in 2011 to ride along with his brother for Team Type 1–Sanofi.
