Donegal County Museum, History museum in Letterkenny, Ireland.

The Donegal County Museum sits in a stone building on High Road and displays collections that document the region's history. The exhibition features archaeological finds, written records, and objects from different time periods.

The building was completed in May 1843 as the warden's house of the Letterkenny Workhouse, designed by George Wilkinson. The museum opened in 1987, received EU funding in 1989, and was extended and reopened by President Mary Robinson on 14 June 1992. Dry rot forced a closure in the 1990s, and it reopened in 1999.

The museum displays how people lived in the region across many generations, from crafts to everyday objects and customs. You can see how local ways of life changed through different periods and what mattered to the community.

The museum occupies the former Warden's House of the Letterkenny Workhouse on the High Road, a building completed in May 1843. Its entrance and galleries are reached from High Road in Letterkenny town centre. The building was extended and reopened in 1992, and after dry rot was found in parts, including an old staircase, it closed and reopened in 1999.

Judith McCarthy became curator in July 1994 and was still in post in July 2024, described as the longest-serving museum curator in Ireland. She took the job after studying at Trinity and earning a Diploma in Arts Administration at University College Dublin.
