The Nubi language (also called Ki-Nubi) is a Sudanese Arabic-based creole language spoken in Uganda around Bombo and Kenya around Kibera by the descendants of Emin Pasha's Sudanese soldiers, settled there by the British. It was spoken by about 15,000 people in Uganda in 1991 (according to the census), and an estimated 10,000 in Kenya; another source estimates about 50,000 speakers as of 2001. 90% of the lexicon derives from Arabic, but the grammar has been massively simplified, as has the sound system.

Although its name literally means Nubian, it bears no relation at all to the Nubian languages spoken by Nubian groups in the south of Egypt and north of Sudan; its name derives from a misuse of the term "Nubi". In fact, most of the soldiers who came to speak it originally came from Equatoria, at the opposite end of Sudan.

Jonathan Owens argues that Nubi constitutes a major counterexample to Derek Bickerton's theories of creole language formation, showing "no more than a chance resemblance to Bickerton's universal creole features" despite fulfilling perfectly the historical conditions expected to lead to such features.
