Dimitry Muravyev (Kazakh: Дмитрий Муравьёв, born 2 November 1979 in Kazakhstanskaya) is a professional road bicycle racer from Kazakhstan. He turned professional in 2002 and has ridden internationally since then, although his primary victories have been the Kazakhstan national road race (2002) and the Kazakhstan national time trial (three times, 2003–2005).
In 2007, he joined the newly formed Kazakh team Astana on the UCI ProTour, where he managed to place 8th in the 2007 Ronde van Vlaanderen and was a member of the winning team in the 2009 Tour de France. On 22 November 2009, it was reported that Muravyev had become one of the 12 members of Astana—and the only Kazakhstani—to rejoin former Astana team director Johan Bruyneel at Team RadioShack. Muravyev later rejoined Astana for the 2012 season.
