	Brosna () is a hamlet in County Offaly, Ireland. It lies in the valley of the Little Brosna River less than one kilometer off the N62 national secondary road. Brosna is deceptive in appearance; the main road through the village is home to families that have been here for several generations. Farming families and a thriving plumbing business operate in and around the hamlet. Like all rural areas in Ireland, Brosna has some neglected old houses, but residents manage to give the place a pretty look with the use of hanging baskets and planted flowers on the bank of the stream that flows through it. At the top of the village a bench awaits walkers or conker collectors in need of a rest or a chat if the day is kind.
