The Osing people are a community living in the eastern salient of Java, Indonesia in the easternmost part of East Java.

They are the descendants of the people of the ancient Kingdom of Blambangan, whose rulers remained Hindus until they were forced to convert to Islam by the Dutch East India Company (VOC) in 1770.

Their population of approximately 400,000 is centered in the province of East Java in the Banyuwangi Regency.

The Osings speak the Osing dialect, which shows influences from both the Javanese and Balinese.
