Ivan Matveyevich Muravyov-Apostol (; – ) was a Russian statesman and writer. Ivan Muravyov-Apostol came from an old notable family. His father was military engineer Matvei Muravyov and his mother was Elena Apostol, granddaughter of a Zaporozhian hetman Danylo Apostol) (Ivan adopted the last name Muravyov-Apostol at solicitation of his cousin in 1800). Ivan Muravyov-Apostol himself was the father of three Decembrists (besides seven other children) – lieutenant colonel Matvey Muravyov-Apostol (1793-1886), lieutenant colonel Sergey Muravyov-Apostol (1796–1826), and warrant officer Ippolit Muravyov-Apostol (1806–1826). Ivan Muravyov-Apostol was born near the town of Borovichi in Novgorod guberniya. In 1773, he was turned soldier of the Izmaylovsky Regiment. In 1776–1777, Ivan Muravyov-Apostol attended Leonhard Euler's boarding school and then was home-schooled after its closing. In October 1784, he joined the staff of Saint Petersburg Governor-General Yakov Bruce first as a legal adviser, then as an aide-de-camp (1785), and second major (1788).

He combined this post with a similar post in Hamburg (1798) and Copenhagen (late 1799). As a diplomat, Ivan Muravyov-Apostol applied efforts to intensify the activity of the Second Coalition against France. He was a polyglot and was able to speak eight foreign languages, including a few ancient ones. In 1800, Ivan Muravyov-Apostol was recalled to Russia and promoted to privy councilor.
