Alexander Alexandrovich Rittikh (September 27, 1868 - June 15, 1930, London) was a political figure of the Russian Empire. On November 29, 1916, he became the last imperial minister of agriculture. A young and energetic minister, son of Alexander Fyodorovich Rittikh, he was distinguished by his exemplary nature, neatness, intelligence, as well as perseverance and a sense of duty. His works and reports, known for their accuracy and clarity, were always published.

Rittikh was responsible for organizing the state requisition of grain during the price scissors of 1916. At that time, inflation of industrial goods significantly outpaced agricultural ones, forcing many peasants to withhold grain from sale. This measure, often associated with the Bolsheviks, was initially introduced by the tsarist government.

In 1918, Rittikh lived in Odessa, and in 1919 he emigrated to England, where he became the director of a Russian bank in London. In 1920, Alexander Krivoshein offered him a position in the Crimean government under General Wrangel, but Rittikh declined.
