The Kingdom of the East Angles, informally known as the Kingdom of East Anglia, was a small independent kingdom of the Angles during the Anglo-Saxon period comprising what are now the English counties of Norfolk and Suffolk and perhaps the eastern part of the Fens, the area still known as East Anglia.

The Angles were one of the main Germanic peoples who settled in Great Britain in the post-Roman period. They founded several kingdoms of the Heptarchy in Anglo-Saxon England. Their name, which derives from the Anglia Peninsula, is the root of the name England. According to Tacitus, writing around 100 AD, a people known as Angles (Anglii) lived east of the Lombards and Semnones, who lived near the Elbe river.
