Thomas Street is a street in The Liberties in central Dublin, Ireland.

The Liberties is an area in central Dublin, Ireland, located in the southwest of the inner city. Formed from various areas of special manorial jurisdiction, separate from the main city government, it is one of Dublin's most historic working class neighbourhoods. The area was traditionally associated with the River Poddle, market traders and local family-owned businesses, as well as the Guinness brewery, whiskey distilling, and, historically, the textiles industry and tenement housing.
