The House of Lobanov-Rostovsky (Russian: Лобановы-Ростовские, literally "Lobanov-Rostovskys") is a Russian princely family that claims their descent from the House of Rurik[1] and whose male-line ancestors were the Rostov princes [ru], who ruled the Principality of Rostov, the area now in the present-day Russia.

[2][3] It originated with Prince Ivan Rostovsky [ru], nicknamed Loban (Лобан) for his wide forehead ("Лоб" means 'forehead' in Russian), who lived at the end of the 15th century and was a descendant of reigning princes of Rostov the Great.

Their coat of arms has a divided shield: the upper part of blue color shows Archangel Gabriel, silver with golden halo and sword.

The lower part in red shows a standing, gold-armed silver stag with a golden collar.

[5] Among the (former) estate of the family is the Lobanov-Rostovsky Palace in downtown Saint Petersburg.
