The Ulster American Folk Park is an open-air museum just outside Omagh, in County Tyrone, Northern Ireland. With more than 30 exhibit buildings to explore, the museum tells the story of three centuries of Irish emigration. Using costumed guides and displays of traditional crafts, the museum focuses on those who left Ulster for America in the 18th, 19th and 20th centuries. The museum is part of National Museums Northern Ireland.

Within the museum there are many restored, original buildings with connections to local families. The park was developed around the Mellon House, the birthplace of Irish-American banker and lawyer Thomas Mellon, founding father of the Mellon banking dynasty. This house and its outbuildings remain in their original location. Visitors can taste samples of traditional Irish and pioneer American foods including freshly baked soda bread and pumpkin pie all made on the hearths and griddles of the exhibit buildings. The museum also includes agricultural displays and an array of farm animals.

The park is open throughout the year, excluding some public holidays.
