Kenmare House, Historic mansion in County Kerry, Ireland.

Kenmare House was the principal residence of the Brownes of Killarney, Earls of Kenmare, on the east shore of Lough Leane. The original 1726 house, designed by the 3rd Viscount Kenmare, was a two-storey structure with dormered attics, steep slated roofs and thirteen bays, with three-bay sections breaking forward on each side of the centre. A servants' wing was added around 1775.

The first Kenmare House was built in 1726 after the 5th Baronet and 3rd Viscount Kenmare recovered the family estates; the Viscount designed it himself as a two-storey house with dormered attics, steep slated roofs and a thirteen-bay front. A servants' wing followed around 1775. The 4th Earl demolished it in 1872, and its successor burned in 1913.

The title Viscount Kenmare comes not from the town of Kenmare but from Kenmare Castle near Hospital, County Limerick, part of the Browne family estate. The Brownes kept their Catholic faith after the Reformation and, unusually, held their lands through the Penal Laws. The 4th Viscount, Thomas Browne, is credited with bringing tourism to Killarney; Tennyson, Wordsworth, Walter Scott and Jane Austen visited in the years that followed.

The house stands on the east shore of Lough Leane, and the Killorglin Road carries the last Kenmare House beside Killarney golf course and the Castlerosse Hotel. The original 1726 building was demolished in 1872, so no garden layout from it survives to walk. Its stable block was converted into the present Killarney House.

The original stable block of the house underwent conversion into what became Killarney House while retaining structural elements from the 18th century. This transformation allows visitors today to see surviving architectural elements of the original property even though the main residence disappeared long ago.
