Aleksei Konstantinovich Karakosov (Russian: Алексей Константинович Каракосов; 1890–1917) was a Russian footballer. He was born in Saint Petersburg and killed in World War I.
Karakosov played his only game for Russia on 4 May 1913 in a friendly against Sweden. In the 75th minute the Russian goalkeeper Dmitri Matrin was injured. Substitutions were not yet allowed, so Karakosov, a midfielder, had to take Matrin's place in goal. He let in two goals.
