Vladimir Sidorkin (born 9 May 1986) is an Estonian former swimmer, who specialized in both long and short course freestyle events.

[1] He represented his nation Estonia in middle-distance freestyle swimming at the 2008 Summer Olympics, and has currently owned a short-course Estonian record in the 100 m freestyle (47.99), set at the 2008 European Short Course Swimming Championships in Rijeka, Croatia.

He led the field with a solid 1:52.12 to register under the FINA B-cut (1:52.53) by about four tenths of a second at the Estonian Invitational Championships three months earlier in Tartu.

[3] Sidorkin put up a marvelous swim in heat two with a monstrous 1:51.27 to blast both a 26-year-old Estonian record and a sub-1:52 threshold for the runner-up spot, falling behind the winner Bryan Tay of Singapore by almost a full second.

Sidorkin's record-breaking feat was not enough to put him through to the semifinals, finishing forty-fifth overall out of 58 swimmers in the prelims.
