Ivan Vladimirovich Lopukhin (Russian: Ива́н Влади́мирович Лопухи́н) (24 February 1756, Oryol Governorate – 22 June 1816, Oryol Governorate) was an Imperial Russian philosopher, mystic, writer and humanitarian.

Lopukhin joined the Preobrazhensky Lifeguard regiment in 1775.

He retired a colonel 7 years later due to health concerns.

After serving as a counselor and later court president on the Moscow Criminal court between 1782 and 1785, he was introduced to rosicrucianism, martinism and freemasonry[1] through his friend Nikolay Novikov and began a career as a writer and printer, while entering civil service.

In 1801 Tsar Alexander I asked Lopukhin to investigate complaints by the Doukhobors, his reports in 1802 leading to their resettlement on the Molochnaya River, along with other religious minorities.
