The Izhorians (sg. ižoralaine, inkeroine, ižora, ingermans, ingers, ingrian), along with the Votes are an indigenous people of Ingria. Small numbers can still be found in the Western part of Ingria, between the Narva and Neva rivers in northwestern Russia.

The history of the Izhorians is bound to the history of Ingria. It is supposed that shortly after 1000, the Izhorians moved from Karelia to the west and south-west. In 1478, the Novgorod Republic, where Ingrians had settled, was united with the Grand Duchy of Moscow, and some of the Izhorians were transferred to the east. The establishment of St Petersburg in 1703 had a great influence on Izhorian culture. Deportations in 1929–1931 dramatically changed the demographics of Ingria. World War II had the biggest impact on Izhorian culture, as devastating battles (Siege of Leningrad) took place nearby.

In 1848, P. von Köppen counted 17,800 Izhorians, and by 1926 there were 26,137 Izhorians in the Russian SFSR. In the 1959 census, however, only 1,100 Izhorians were counted in the USSR. In 1989, 820 self-designated Izhorians, 302 of whom were speakers of the Ingrian language were registered. 449 Izhorians lived in the territory of the USSR. According to the 2002 Russian Census, there were 327 Izhorians in Russia, of whom 177 lived in Leningrad oblast and 53 in St Petersburg. There were also 812 Ingrians in Ukraine according to Ukrainian Census (2001) (more than in Russian Federation and Estonia altogether) and a further 358 Ingrians in Estonia.

Their language, close to Karelian, is used primarily by members of the older generation. Izhorian, along with Finnish, Karelian and Vepsian, belongs to the Northern Baltic-Finnic group of the Uralic languages. Izhorian consists of four dialects: Soikola, Hevaha (or Heva), lower-Luuga and Oredezhi — from the names of the Soikola (Soikinsky) peninsula and the Heva, Luuga (Lauga) and Oredezhi rivers.
In 1932–1937, a Latin-based orthography for the Izhorian language existed, taught in schools of the Soikino Peninsula and the area around the mouth of the Luga River.Kurs, Ott (1994). . GeoJournal 33.1, 107-113.. Several textbooks were published, including, in 1936, a grammar of the language. However, in 1937 the Izhorian written language was abolished and mass repressions of the peasantry began.
The Izhorians and the Votes are generally Orthodox, while the other Finnic inhabitants of Ingria, the Ingrian Finns, are generally Lutheran. Some pre-Christian traditions exist, also.
