Minard Castle is a 19th-century castellated mansion on the north-western shore of Loch Fyne Argyll and Bute, on the west coast of Scotland,[1] in the parish of Kilmichael Glassary.

The current structure is the enlargement of an older house carried out around 1848 by the architect John Thomas Rochead.

The house was reconstructed as a Tudor Revival style of mansion in 1842 by John Thomas Rochead.

In 1850, William Hamilton extended the house, adding a facade consisting of a number of large rooms to the front of the old mansion.

Later, the house was sold to the Scottish submarine communications cable pioneer, John Pender.
