Westport House in Westport, County Mayo, Ireland, is a Georgian country house, historically the family seat of the Marquess of Sligo and the Brownes. The house was designed by the architect Richard Cassels with later additions by Thomas Ivory and James Wyatt.
The title and the house were separated in 2014, following the death of Jeremy Browne, 11th Marquess of Sligo, who left the estate to his five daughters. His titles passed to his first cousin, Sebastian Ulick Browne, a residential estate agent in Australia.
In 2017, the house was purchased by the Hughes family, owners of Portwest.
