Sir Ralph Abercromby Anstruther, 4th Baronet, was a landowner and designer active in the 19th century.
In 1818 Anstruther inherited the Balcaskie estate in Fife, Scotland. From 1826, until his death in 1863, he embarked on a programme of improvements and restoration there, employing both William Burn and David Bryce to make additions and alterations to the house and W.S. Gilpin and William Nesfield to give advice on the garden and park and modify the planting.
