Metropolitan Macarius (Russian: Митрополит Макарий, secular name Mikhail Andreyevich Nevsky, Russian: Михаил Андреевич Невский; 1 October 1835 – 2 March 1926) was the Metropolitan of Moscow and Kolomna from 1912 to 1917, an outstanding missionary and enlightener of the masses in the Altai region (people used to call him the "Siberian pillar of Orthodoxy" and "Apostle of the Altai").

Born to a family of a sexton, Macarius graduated from a theological seminary in Tobolsk (1854) and joined the Altai Mission, which had been set up by the Holy Synod with the purpose of converting the people of the Altay region to Christianity.

In 1883, he was appointed head of the Altai Holy Mission and raised to the dignity of archmandrite, and then consecrated as Bishop of Biysk and vicar of the Tomsk eparchy.

In 1913, Macarius became an honorable member of the St Petersburg Theological Academy.

In 1956, Macarius' remains were transferred to Sergiyev Posad and placed under the Dormition Cathedral of the Trinity-St. Sergius Lavra.
