Balla (pronounce Bal) (Irish: Balla) is a village in County Mayo, Ireland on the N60 National secondary road, the main road between Castlebar and Claremorris. Balla has only one street. It is notable for its round tower. It formerly was a significant shop and market centre. In recent decades it fell into decline and lost its railway station, but has enjoyed something of a revival as a residential area for people working in Castlebar.
