Arthur Cherep-Spiridovich (1858 — 22 October 1926) was a Russian Count who moved to the United States following the Bolshevik Revolution. He was a Tsarist general and white Russian loyalist. He was involved in Pan-Slavism and White Russian activism, including various chivalric orders and cultural organisations, amongst the diaspora community in America. Spiridovich is perhaps best known for authoring a book positing a concise conspiracy consisting of 300 Jewish families entitled "Secret World Government or The Hidden Hand".
