Lived 1835 – 1919 (aged 83–84). Arthur Cassini was a Russian diplomat.

Artur Pavlovich Cassini, Marquess of Capizucchi di Bologna and Count Cassini (; 27 November 1835 – 19 October 1919), known as Arthur Cassini, was a Russian aristocrat and lifelong diplomat who served the Russian Empire for 55 years during the 19th and early 20th centuries. During his tenure, he served most prominently as ambassador to China during the Triple Intervention and the negotiations over the lease of Port Arthur; as ambassador to the United States for seven tumultuous years that saw the Spanish–American and Russo-Japanese wars; and as ambassador to Spain during the Algeciras Conference.

Having set out the tone of his mission, when the Sino-Japanese war ended, he led the way for the group of European powers that compelled Japan to withdraw her demands for territory amongst her war gains, in what became known as the Triple Intervention. Immediately after, and against the efforts of the British Government he was instrumental in arranging for the acquisition for Russia of long term concession of Port Arthur and Talien Bay on the Liaotung peninsula, as well as rights to link these by railroad to Russian lines. Recognizing the strategic importance of his role, Cassini is said to have told his niece and adoptive daughter Marguerite: "To possess the East, Russia must possess the Liaotung peninsula."
