The Ingaevones (Latin: [ɪŋɡae̯ˈwoːneːs]) or Ingvaeones (English: /ˌɪŋviːˈɒnɪz/) were a Germanic cultural group living in the Northern Germania along the North Sea coast in the areas of Jutland, Holstein, and Lower Saxony in classical antiquity. Tribes in this area included the Angles, Chauci, Saxons, and Jutes.
The name is transmitted in two different forms in ancient sources: Tacitus provides the form Ingaeuones, while Pliny the Elder has Inguaeones. Most scholars derive the name from the god or hero attested under the name Yngvi in later Norse sources, and thus believe Pliny's form is the original one. Hence the postulated common group of closely related dialects of the "Ingvaeones" is called Ingvaeonic or North Sea Germanic.
