''' Tengréla ''' (also spelled Tingréla) is a town in the far north of Ivory Coast. It is a sub-prefecture and the seat of Tengréla Department in Bagoué Region, Savanes District. Tengréla is also a commune.

The French explorer René Caillié stopped at the settlement of Tengréla, which was then a large walled village, in January 1828 on his journey to Timbuktu. He was travelling with a caravan of 500 to 600 people and 80 donkeys transporting kola nuts. In his book Travels through Central Africa to Timbuctoo published in 1830, he spelled the name of the village as "Tangrera".
