Smarhon (Belarusian: Смаргонь [smɐrˈɣonʲ]) or Smorgon (Russian: Сморгонь; Lithuanian: Smurgainys; Polish: Smorgonie; Yiddish: סמאָרגאָן) is a town in Grodno Region, Belarus.

Amid the disastrous retreat from Russia in 1812, Napoleon left the remnants of the Grande Armée at Smorgon on December 5 to return to Paris.

From 25 June 1941 until 4 July 1944, Smarhon was occupied by Nazi Germany and administered as a part of the Generalbezirk Litauen of Reichskommissariat Ostland.

Up until World War II, Smarhon was widely known for its baranki,[5] traditional Eastern European ring-shaped bread rolls, similar to bagels and bubliki.

Polish-Lithuanian journalist Adam Kirkor wrote in the encyclopedia Picturesque Russia: "In Smorgon, Oshmyany district, Vilna province, almost all the petty bourgeois population is busy baking small bubliki, or kringles, which are widely known as Smorgon obvaranki.
