Éragny (sometimes unofficially called Éragny-sur-Oise) is a commune in the northwestern suburbs of Paris, France. It is located 26.3 km (16.3 mi) from the center of Paris, in the "new town" of Cergy-Pontoise, created in the 1960s.

Inhabitants are called Éragniens.

It noted a very light inflecting of the growth the 10 last years, proof that one reached the nominal size, after the very strong growth of 1975/1982. On the contrary, Cergy-Pontoise, over the same period a growth of 16.16% posted (1,049,598 into 90, 1,105,464 into 99), showing that the area is still in fast progression. The current density (of 1999) is of 3,588 inhabitants by km². It very in a decade of that of Paris (of less than 10,000 hab/km² in the 1st with more than 40,000 hab/km² in the 11th, given in 1999), and with the top of the average density of Île-de-France (900 hab/km²), which is normal for an urban zone.

The distribution and approximately of 50/50 for the area, the proportion collective/individual is also 50/50, which shows a balance in the distribution. Development and population growth was at a peak between 1975 and 1982 but has declined recently (18 in 9 years). This weak current rate of construction of residences reflects demand. Density of residences is still low for an urban area at 1200 /km².

Situated on the Oise river, Éragny sur Oise remained a small village until the 20th century. Its original inhabitants probably settled around the town's fountain during the Roman period and named the place Heriniacus or Areniacus. The site changed names several times over the following centuries - Eraisgny, Eraigny, Erargny, and finally settling on Éragny by the 10th century.
