The Osing language (Osing: Basa Using; Indonesian: Bahasa Osing), locally known as the language of 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 dialect.

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.
