Dmitry Konstantinovich Kiselyov (Russian: Дми́трий Константи́нович Киселёв, born April 26, 1954 in Moscow) is a Russian journalist. In December 2013 he was appointed by Russian President Vladimir Putin head of the new official Russian government owned international news agency "Rossiya Segodnya" (Russia Today), a 2,300 person organization made up largely of the former "RIA Novosti" news agency and the shortwave radio station "Voice of Russia". He also serves as deputy director of Russian state TV holding company VGTRK.

Many of his comments have been controversial and have been labelled right-wing; he has gained particular notoriety in the west for his commentary on homosexuals and his statement made during the 2014 Crimean crisis, that Russia is "the only country in the world capable of turning the U.S.A. into radioactive dust." Kiselyov considers himself a liberal and he says of his opponents as: "Parkhomenko and Navalny. Why they are liberals? They are absolutely totalitarian people. I am a liberal, because I put up with them." Also he doesn't consider himself as homophobic.
