Roman Arkadyevich Abramovich (born 24 October 1966) is a Russian billionaire businessman, investor, and politician.

Abramovich is the primary owner of the private investment company, Millhouse LLC. Abramovich is best known outside Russia as the owner of Chelsea Football Club, a Premier League football club. According to Forbes, Abramovich's net worth in 2016 was $8 billion, making him the 13th richest person in Russia, and the 680th richest person in the world.

By 1996, at the age of 30, Abramovich had become so rich and politically well-connected that he had become close to President Boris Yeltsin, and had moved into an apartment in the Kremlin at the invitation of the Yeltsin family. In 1999, and now a tycoon, Abramovich was elected governor of Russia's remote, far eastern province of Chukotka, and has since lavished £112 million (€132 million) on charity to rebuild the impoverished region. ​
