Ivangorod (Russian: Иванго́род, IPA: [ɪvɐnˈɡorət]; Estonian: Jaanilinn; Votic: Jaanilidna) is a town in Kingiseppsky District of Leningrad Oblast, Russia, located on the east bank of the Narva river which flows along the Estonia–Russia international border, 159 kilometers (99 mi) west of Saint Petersburg, 218 kilometers (135 mi) east of Tallinn, Estonia. The town's population was recorded as 9,854 (2010 census); 11,206 (2002 census); 11,833 (1989 Soviet census). As of 2025, the population of Ivangorod was estimated to be 9,878.

Ivangorod is a major border crossing point and a railway station on the Tallinn–Saint Petersburg line. It is located just opposite to the Estonian town of Narva. The town is the site of the Ivangorod Fortress, a prominent fortification monument of the 15th and the 16th centuries.

In 1470, the chronicles first mentioned the “New Village on the Narova River,” the future Ivangorod.

In 1473, the First Pskov Chronicle mentioned Pskov posadniks and boyars who were sent to the “New village on the Narova,” opposite the city of Rugodiv (Narva), to meet the Livonians along with Novgorod envoys. According to historian Vladimir Kostochkin: “On the basis of this village Ivangorod then grew.”

The fortress, established in 1492 during the reign of Ivan III, the grand prince of Moscow, took its name (literally: Ivan-town — gorod in Russian means "town" or "city") from that of the tsar. The fortress was built along with a series of other fortifications on the border with Livonia. Ivan was said to have blinded the fortress's architect to prevent him from building such a structure for anyone else. A battle between Russian and Swedish forces took place at the fortress in 1496.

The location was chosen in advance: already in the 1480s the Grand Prince instructed his envoys to Lithuania to inquire in detail about harbors on the Baltic Sea. At that time the Baltic trade route acquired prime importance for the Russian state, for its economic and cultural development, and also for its political relations with European countries. Only through the Baltic Sea could trade be conducted independently of foreign control and interference. The town was intended to become the first seaport of the Russian state and, at the same time, a fortress on the Baltic.

The original fortress laid down in 1492 was besieged and destroyed by the Swedes in 1496. After this the Russians restored and expanded it. In German documents of the late 15th century it was known as a “counter-Narva.” The Ivangorod Fortress with its mighty stone walls and ten towers was the first Russian defensive work with a regular rectangular plan.

In 1565, when Tsar Ivan the Terrible divided the Russian state into the Oprichnina and the Zemshchina, the town became part of the latter.
