Sir Hector Mackenzie, 4th Baronet

Sir Hector Mackenzie, 4th Baronet of Gairloch (September 1758-26 April 1826) was a Scottish landowner and baronet. He succeeded his father Sir Alexander on 13 April 1770. He held the office of Lord-Lieutenant of Ross-shire.

The Mackenzies of Gairloch were clan leaders in the traditional sense and were known for their attachment to their tenants. During the Highland Clearances of the 19th century, Sir Hector Mackenzie and his sons Sir Francis and Dr. John Mackenzie refused to evict a single tenant, despite the estate running at a loss. As a result, evicted Highlanders from other communities came to live in the area and has caused Gairloch to maintain a thriving community to the present day.
