Usansolo is a neighbourhood located in the east side of Galdakao (Biscay) in Spain, 2 km away from the town center. With few baserris, its population began rising after the railway station was built in the 19th century, when flats started being built. It has 3,696 inhabitants as of 2005. Due to its distance from the town center, there have been some initiatives to make it independent.
