Cuba (Tsucuba), anglicized as Shuba and also known as Urcibar in neighboring Lopa, is a minor Kainji language of Nigeria, spoken by a thousand people in Kebbi State.
The name Rerang (Oleran) subsumes both Cuba and the closely related Lopa language that surrounds it.
Blench concludes that Cuba is more closely related to Shen (Laru) than it is to Rop (Lopa).
Cuba is spoken in the large villages of (Cifamini), (Gungun Tagwaye) and (Kwanga); and the minor villages of (Yumu), (Bakari) and (Ambu shiri).
