Tirabad is a village in Powys, Wales. The name means "the abbot's land"; the village belonged to Strata Florida abbey in the Middle Ages. The village is located on the edge of the Crychan Forest and is 8 kilometres (5 mi) south of Llanwrtyd and 18 kilometres (10 mi) north of Llanymddyfri. Many people had to leave the village during World War II as the military used the area for artillery training, but the village expanded substantially in the 1950s, when the Forestry Commission, now defunct, began tree plantations and built about 25 houses, a school, a village hall and a shop for their employees.
