The Osing language (Osing: Basa Using; Indonesian: Bahasa Osing), locally known as basa Banyuwangi, is the Modern Javanese dialect of the Osing people of East Java, Indonesia. The Osing dialect uses a special diphthongization (changing the vowel [i] to [ai] and the vowel [u] to [au]) which is not found in any Other Javanese dialects. They are primarily distributed in Banyuwangi Regency, but can also be found in the eastern part of Jember Regency, particularly in districts of Panti and Wuluhan.

Some Osing words have the infix /-y-/ 'ngumbyah', 'kidyang', which are pronounced /ngumbah/ and /kidang/ in standard Javanese, respectively.

A dictionary of the language was published in 2002 by Hasan Ali, an advocate for the language's use in Banyuwangi.
