Otxarkoaga-Txurdinaga is the third district of the city of Bilbao (Biscay), in the Spanish Basque Country.

In these areas existed vineyards for the elaboration of the traditional Txakoli white wine, this has given the inhabitants the nickname of Matxorris, from Basque language Mahats=grape and orri=plant.

The Basque Football Federation has its offices in the area, on Julian Gaiarre Etorbidea.

The Bilbobus and BizkaiBus bus lines have stops in the district.

In 2017, line 3 of the Bilbao metro opened, with the Otxarkoaga and Txurdinaga stations in the district.
