Lopa or Rop (Ollop) is a minor Kainji language of Nigeria.
Lopa people neighbouring the Busa language have shifted to that language.
The name Rerang (Oleran) subsumes both Lopa and the closely related Cuba language (Urcibar) that it surrounds.McGill, Stuart. 2012. The Kainji languages. Ms, School of Oriental and African Studies, London, 30 August 2012.
Blench (2019) lists Tsupamini as a related variety or dialect.
Name The name Lopa likely comes from the name lópár (Lapar), which refers to both the Rop and the Shuba. Cover terms referring to both Urcibar and Ollop speakers are [dɔ̀ɾìɾáŋ̃ ] (one person), [òːɾìɾáŋ̃ ] (many people), and the language [òlːèɾáŋ̃].

Lopa speakers call themselves [dɔ̀ɾóp] (one person), [òːɾɔ́p] (many people), and the language [òlːɔ́p].
